This transducer vibrates with a certain acoustic intensity at the typical frequency of 1 MHz, and the ultrasound waves are propagated into biologic tissue. The piezoelectric element in the composite structure is made from PZT ceramics; the clamped titanium membrane is tuned to the frequency of the resonator. Since a precise adjustment of the frequency of the transducer (which is exposed to the acoustical milieu of the air and other substances) is required, it is necessary to know the frequency spectrum of the vibrating composite resonator. This is influenced by a number of parameters. Tuning this composite structure is not a simple step in the manufacturing process, because the machining of the membrane is irreversible. In this paper, the completed investigations of the approach to the analytical solution of coupled vibrations of the piezoelectric resonators are presented, including the frequency spectra of the PZT disc-shaped resonator with a defined ratio of the diameter/thickness. However, this approach fails in the case of the real ultrasound transducer resonant structure (i.e., the disc-shaped resonator attached to the mechanically clamped metal membrane). Therefore the behavior of the vibrating structure has to be solved by some FEM method. In the described case the standard IEEE impedance/admittance measurement method and FEM simulation were used. The results allow an assessment of the suitability of the composite piezoceramic resonator in the terms of resonant frequencies, and tuning of the metal membrane to the appropriate resonant frequency.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130919566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We may use 103–105 spectra; each spectrum being a vector with 102–104 coordinates. We thus face the so-called “curse of dimensionality”. We look for a method to reduce the size of this data-space, keeping only the most relevant information. As a reference method, we use principal component analysis (PCA) to reduce dimensionality. However, PCA is an unsupervised method, therefore its subspace was not consistent with the parameter. We thus tested a supervised method based on Sliced Inverse Regression (SIR), which provides a subspace consistent with the parameter. It also shares analogies with factorial discriminant analysis: the method slices the database along the parameter variation, and builds the subspace which maximizes the inter-slice variance, while standardizing the total projected variance of the data. Nevertheless the performances of SIR were not satisfying in standard usage, because of the non-monotonicity of the unknown function linking the data to the parameter and because of the noise propagation. We show that better performances can be achieved by selecting the most relevant directions for parameter inference. Preliminary tests are performed on synthetic pseudo-line profiles plus noise. Using one direction, we show that compared to PCA, the error associated with SIR is 50% smaller on a non-linear parameter, and 70% smaler on a linear parameter. Moreover, using a selected direction, the error is 80% smaller for a non-linear parameter, and 95% smaller for a linear parameter.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131325984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are several faults that may arise in machines increasing noise and vibration. Cogging is one of the main faults in Permanent Magnet Synchronous Machines (PMSMs). Tools for the diagnosis of cogging are needed to detect the machines that do not fulfil the quality requirements. The usual methods found in bibliography to assess cogging are Motor Current Signature Analysis (MCSA) or directly measuring it by means of a torque sensor. This paper studies the feasibility of the alternative and unpublished method of vibration signals measured with accelerometers to evaluate cogging. In this paper a machine is designed and manufactured, in order to measure the effect of cogging in the vibration of the machine. The tested machine allows to apply several cogging levels, and the vibrations and the torque are measured with the machine running at several rotational speeds. Especially at lower rotational speeds, the effect of the cogging is clearly observed in the spectra of the torque. However, the spectra of the vibration signals do not show the effect of cogging torque, since at the cogging frequency the amplitudes do not correspond to the cogging levels.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121141808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SEM control structure uses the mathematical model of the servomechanism to generate the final active damping correction signal. This type of control structures typically suffer from the high dependency on compliance mathematical model with real physical system of the servomechanism. The compliance has a major effect on the effectiveness of active damping but also to the inherent stability of control system. Otherwise, the mathematical model does not produce the correct frequency of residual vibration and because of this can hardly damp the real servomechanism vibration. This is why we focus on self-adaptation of the active adaptation of mathematical model parameters using an artificial intelligence technique such as fuzzy logic. Fuzzy systems are widely used in modelling of unknown and dynamically changing parameters likewise in uncertainty compensation. Fuzzy modelling approach of certain parameter of the servomechanism model is going to be presented and validated.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131181633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the current industrial wireless communications are based on existing standards like IEEE 802.11, IEEE 802.15.1 or IEEE 802.15.4 and additionally proprietary protocol extensions are applied over them. These communication systems cover a wide range of industrial applications but they lack robustness when it comes to tight real-time requirements for factory automation. Hence, new schemes for the physical layer, along with new media access techniques, for industrial wireless communications must be proposed. Among the upcoming technologies, modulation candidates for 5G and cognitive radio might be promising solutions. In this article we analyse FBMC-OQAM, GFDM-OQAM and WCP-COQAM modulation candidates for 5G in terms of bit error rate, power spectral density and spectral efficiency over highly dispersive channels. From this analysis, on the one hand, we assess the suitability of these modulation systems for industrial wireless communications based on cognitive radio. On the other hand, we provide additional details about how windowing affects the protection against highly dispersive multipath channels and the spectral efficiency in WCP-COQAM.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114730736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the different types of microgrids, dc systems are becoming more popular due to their advantages over conventional ac systems. However, their control techniques differ from the ones employed at ac networks, and depending on the device type—either generation, storage systems or loads—alternative control techniques need to be developed. Therefore, in this paper an experimental dc platform is developed with the aim of testing and evaluating these kind of control strategies. This test bench consists of a bidirectional four switch buck-boost converter together with a TMS320F28335 DSP for the implementation of the control strategy on each power converter. The proposed platform is suitable for integrating these systems at a 48 V dc bus and facilitates the evaluation of a wide range of control strategies as they are implemented in the Matlab/Simulink® environment. In this case, the validation of the experimental platform has been carried out by implementing a virtual-impedance-based control technique. The experimental results included in the paper corroborate the suitability of the platform for the evaluation of control techniques for dc microgrids.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130163070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Visual inspection needs to be easy to apply and quickly carried due to time constraints on the airport. The robot is able to navigate autonomously around the aircraft, stop at checking positions and point the camera towards the region of interest. Items to inspect can be detected in the image acquisition thanks to some knowledge on those items. This knowledge has various forms: picture database, three dimensional models, aircraft markings, item configurations and marking dispositions. During its inspection tasks, the robot can warn its human operator that something is wrong and if possible ask for a fast human intervention for examples if there is still the chock in front of the landing gear or the protection on a pitot probe. At the end, it provides all its diagnoses and asks the human operator to validate or refute each of them. The article proposes fast visual detections and verifications of exterior aircraft elements.

This combines the ubiquity of the IoT with the processing capabilities of cloud computing to generate insights that help to optimize the decision making process. The increasing demand of data and the explosion in the number of sensing devices, which might be highly constrained in terms of communication, battery and computational power, introduce new challenges that need efficient IoT-Cloud architectures. With this in mind, we extend MQTT, the de facto IoT communication protocol, using a fog computing approach that introduces a low complexity computational layer between the Cloud and IoT nodes. In this approach, the MQTT broker, which is in charge of relaying data from publishers to subscribers, is placed at the fog layer. The purpose of introducing an intermediate layer to this particular scenario is to: i) predict future data measurements through prediction techniques; ii) operate as a gateway to upper layers; and iii) provide the capability to offload computationally expensive data processing jobs from the Cloud to the Fog, minimizing additional latency and operational expenses. With this architecture, the transmissions required from IoT devices may be reduced, since the publishers would only need to update the predicted data in case of mismatching. We validate our approach with an energy consumption analysis and simulations of different Machine Learning algorithms on a real dataset, and compare it with the traditional MQTT scheme.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"375 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133739158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
