In particular, we extend some well-known nullspace-based blind calibration approaches, proposed for fixed sensors with affine responses—i.e., with unknown gain and offset for each sensor—to that difficult case. These state-of-the-art approaches assume that the true data lie in a known lower dimensional subspace, so that in practice sensors can be calibrated by projection of the uncalibrated observations to this subspace. A robust extension was recently proposed in order to provide less sensitivity to noise. In this paper, we show that such methods (including the robust extensions) are very sensitive to outliers and we propose new extensions able to deal with such issues. For that purpose, we assume the outliers to be rare events, which can be modeled as a sparse contribution to the low-rank observed data. Using such an assumption, we separate sparse outliers from the low-rank data, so that we can perform calibration. We show that the proposed approach is able to handle up to 10% of outliers in the data without major impact on the calibration accuracy while state-of-the-art methods are already sensitive to the presence of one unique outlier.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133927041","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}

One source of noise and vibration is the torque ripple. Torque ripple can be generated by an inappropriate machine control tuning and by the inherent torque ripple of the machine. In permanent magnet machines, the inherent torque ripple is composed by three components: electromagnetic torque, reluctant torque, caused by the winding magnetic field, and reluctant torque caused by the permanent magnet magnetic field, commonly known as cogging torque. In order to assess the torque ripple at each working point, the electromagnetic analysis using a Finite Element Method (FEM) is a very accurate solution. In a dynamic simulation the high computational load is the main drawback of the FEM analysis. To overcome this problem, in this paper the use of a mixed approach is proposed, in which the parameters of a dynamic vector model are previously adjusted using FEM characterization. The aim of this strategy is to do just one complex FEM simulation, so later a quicker dynamic model can be used. In this article, an adjusted dynamic vector model of a Permanent Magnet Synchronous Machine (PMSM) is presented. The inputs of the model are the phase voltages and the rotor position. The outputs are the currents, the flux linkages and the total electromagnetic torque, including all the parasitic components of the torque ripple. The advantages of this model are the reduction of simulation time and the possibility to integrate it in a more general dynamic simulation platform.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132181365","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}

In the past, a measurement system with two 8 channel DSA cards was developed. This system has provided to be reliable. However, the accuracy of the shaft angle measurements was to be found of lower accuracy, but still considered adequate for the purpose of induction motor fault diagnostics. The angular position is measured with the use of an IRC sensor, where the actual absolute angle is sampled synchronously with all other channels with sampling frequency in the order of tens of kilosamples per second. During more advanced experiments, the currently used method had shown limitations (lower resolution, problems with velocity calculation). To solve this problem, a new improved method, based on a combination of commonly known angular position and velocity measurement, is proposed. The performance is evaluated by simulations. Some common methods for precise measurements of angular velocity and angular speed oscillations are briefly described, along with their advantages and disadvantages. The simulation results of the proposed method are compared with the method currently used. The possible implementation of the proposed new measurement method with the use of the existing hardware is discussed.","PeriodicalId":358140,"journal":{"name":"2017 IEEE International Workshop of Electronics, Control, Measurement, Signals and their Application to Mechatronics (ECMSM)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124051520","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}

Implementation of any complex digital circuit requires digital synthesis and therefore a digital standard cell library. Absence of the digital libraries in core design kits provided by the foundries is a significant hurdle for academic institutions to design complex electronic systems. Therefore, design of a custom digital library becomes a necessary step for a successful mixed-signal design. In this paper, the design of such a custom digital library is presented. The library was designed in 28nm CMOS technology and tailored for usage in mixed-signal applications. The composition of available cells and its effect on the performance and area of the synthesized block are discussed. Moreover, different approaches to the transistor dimensioning are compared regarding design effort and performance. To verify the library and the design flow, a serial-to-parallel interface (SPI) demonstrator chip was designed, fabricated and tested. The measurement results correspond to the simulation results and were used to further improve the library and the design process. Finally, the performance of the library is compared to two other digital libraries, one of which is a state-of-the-art commercial library based on high performance 45nm silicon-on-insulator (SOI) CMOS technology. The designed library offers low leakage power and low area consumption while allowing moderate speed which is well suited for the usage in digital control blocks within the mixed-signal systems.","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":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129110845","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}
