Three-phase diode bridge rectifiers with complex transformer configuration are normally used in this converter, which do not have regenerative capability. Three-phase or single-phase pulsewidth-modulated (PWM) rectifiers are used at the front end to achieve regenerative capability and input power factor controllability. However, the semiconductor devices are operated at high switching frequency due to two level voltage operation of these rectifiers. The single-phase PWM rectifier requires less number of switches and current sensors than the three-phase configuration. However, in this configuration, lower order harmonic currents circulate among the power cells through transformers; though these are absent in source currents. In this paper, a new configuration with single phase PWM rectifier based power cells is proposed to achieve multilevel voltage operation at both the input and output sides. Hence, the semiconductor devices of the rectifiers can also be operated at low switching frequency to draw quality source currents. Moreover, the lower order harmonic currents are also absent among the power cells. Analysis and simulation results are presented to confirm the effectiveness of the converter.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130667677","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}

Many existing techniques are able to provide high recognition rate, but at the cost of long training time. In this work, we present a neural network based approach to reduce the training time while maintain the high recognition rate. The main idea is to perform a preprocessing stage to partition the training data prior to the training stage. A multi-stage approach is then used to deal with various types of input source. Our experiments on real image datasets have demonstrated that the balance between the training time and recognition time can be achieved using the proposed method.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116695960","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}

Furthermore, since frequency symbol spreading (FSS) can mitigate the effect of frequency selective fading, it is useful for improving the BER performance. However, FSS cannot be applied to MIMO system with adding forward error correction (FEC) due to interference of the transmit antennas. In this paper, we consider the difference of the transmitted power for each user and the difference of the distance from base station (BS) to each user in general mobile wireless communications, we propose that applying FSS and adaptive subcarrier block (ASB) method with considering the imbalanced transmitted power for MU-MIMO.

It is known that classical image based visual servo control scheme has some problems, e.g., image space singularities and local minima. To tackle this issue this study applied a virtual composite camera model and a 3D visual Cartesian space to calculate the full-rank image Jacobian for visual tracking control. The advantage of this approach is that the image Jacobian obtained will be always non-singular for robustness. This research employed a distributed embedded system including two DSP boards to implement the above visual servo algorithm. The experimental results demonstrate that the proposed visual servo system is feasible in an embedded system.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116979684","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}

The special features of the proposed predictive current control method include no need of converter model in prior and reduction of calculation time required for control. Since the proposed control method is modeless predictive control, the parameter variation will not affect the control performance as compared to model-based control approaches. Both simulation and experimental results will be presented to confirm the effectiveness of the proposed modeless predictive current control method. Experimental results are derived from a DSP-based three-phase AC/DC converter with the following specifications: the output voltage = 380 V, input voltage = 220 V/AC, and output power = 1000 W.

Free-form laser deposition can be used for 3D printing of metal parts, repair of high value components and wear resistant surface coating with minimal damage to the existing features, because the heat affected zones and dilution of melt pool into the substrate are controlled. The material for deposition is metal powder. To avoid oxidation of powder during melting and fusion, it is imperative to shield, therefore the powder is mixed with an inert gas. The mixing also increases the flow-ability of the powder and helps in generating a uniform clad. We have designed a powder delivery system and this powder delivery system has been integrated with a 100 W laser, focusing optics and a positioning system for the design of the cladding setup. The experimental setup is able to produce free form clads in two and three dimensions with a consistent quality, using a low power (100 W) laser as compared to traditional setups with high power lasers (2-3 kW).","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128281078","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}

The development of finite state machines is facilitated by means of a procedural programming model. Algorithmic descriptions of circuits, memory initialisers and parameters are supported by means of scripting.

However most existing control methods for this goal require either online force sensing or the exact parameters of the robot, which is usually difficult and expensive. In this paper, two mobile manipulators are utilised to verify a simple cooperative manipulation control scheme. The mobile platforms track offline designed trajectories in order to maintain a formation, while the robotic arms holding a rigid object on top convey compliant behaviours so that the internal force likely to be caused by the motion error of the platforms is suppressed. The dual-arm control is in a Leader-Follower structure and the compliance feature is achieved with a classic PD controller with gravity compensation, easy to implement in industrial application. The effectiveness of the control system is exhibited in experiments.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"58 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134408750","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}
