Introduced here is a new class of low cost AC-DC high power factor/low harmonic rectifiers. With active zero current resonant switch (ZCS) added to the diode bridge rectifier, the converter is capable of drawing a high quality input current waveform naturally at nearly unity power factor, without switching losses and current line transducers. Thus, a simple single phase or 3 phase AC-DC high power factor rectifier is obtained. Full theoretical analysis is effectuated. Simulation and experimental results are supplied to demonstrate the validity of the concept.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124261888","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}

A typical disk drive actuator can be modeled as a second order dynamics for low frequencies. However, the higher frequency response shows resonant behavior which are difficult to model. We discuss the use of IMC structure for designing servo-controllers for disk drives. In this method, a second order nominal model of the plant is used to design an H/sub 2/-optimal controller to attain minimum integral-error-square (ISE) performance. Multiplicative uncertainty bound is defined by the difference between the actual frequency response and the response of the nominal model. The uncertainty bound is used to decide robust stability and robust performance bounds. The H/sub 2/-optimal control is then augmented by a low-pass filter with sufficient high frequency roll-off to ensure robust stability and robust performance. Tuning of only one parameter of the IMC filter makes this design method easy and convenient. Simulation results for the designed controller are presented.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"AES-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126498238","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 order to make machine visual processing more practical and powerful, it is important to develop a technique for understanding various noise superimposed images. To solve this problem, a two-stage association technique is proposed based on network constraint analysis. In the first stage, strict screening of the memory which contains reference images is performed employing an acquired noisy image to yield an intermediate image, while in the second stage, rather weaker screening of the memory is done by the intermediate image and depth first search is applied to those surviving image pieces in the memory to finally obtain an associated image. An algorithm to speed up the association process is also employed in the second stage. Performance of the two-stage association is examined by an experiment employing real noisy alphabetical images and satisfactory results are obtained.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125770044","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 main feature of fuzzy phase-lead compensators is to have parameters for effectively compensating phase characteristics in control systems. We show an important theorem, which realizes a phase-lead compensation, by introducing concept of frequency characteristics. Two design procedures of fuzzy phase-lead compensators are presented: cases of linear plant and unknown nonlinear plant. We apply one of the design procedures to tank level control which is a non linear system with dead time. Simulation results show validity of the design method.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130180995","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 inverter is nonlinear which causes instability problems in some specific working points of the AC machine and it emits acoustical noise due to the switching frequency. Nonlinearities like dead-time in the power devices, a load dependent DC link voltage ripple and the voltage drop across the switches are modelled and compensated by improved modulation techniques in order to obtain an ideal inverter. Different feedback and feedforward techniques are proposed. The acoustic noise is reduced by using a random modulation strategy. Measurements show a significant improvement by using feedforward and feedback techniques for linearizing the inverter as well as an improvement in reduction of the acoustic noise emission is achieved by using random modulation. It is concluded that a combination of a random modulation strategy and feedforward/feedback techniques gives an almost ideal AC motor drive system.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131384727","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}

This paper outlines a methodology for the design of an intelligent controller to perform optimal control of a nonlinear system adaptively, using emerging technologies of fuzzy logic (FL) and artificial neural networks (ANN). FL is utilized to incorporate the available knowledge into the control system, and ANN technology is applied to adaptively provide an optimal control strategy based on some performance criteria. The technique is tested on a system that consists of a DC motor (a linear time-invariant (LTI) system) and a thermal system (a time-varying nonlinear system). Performance criteria such as tracking accuracy, cost, robustness, are considered, and the results are presented in this paper.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130051137","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}

To implement co-operation, a powerful behavioural control architecture, the behaviour synthesis architecture, has been developed, along with complementary sensor based communications and appropriate sensing and actuation systems. These ideas have been implemented on two mobile robots, which demonstrate co-operative behaviour by acting in unison to transport a pallet through an unstructured environment.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115994902","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}

No prior knowledge of the structure of the nonlinearities is required, although a knowledge of the dependent variables within the nonlinearities is assumed. The identification strategy involves the use of Walsh functions which are particularly suitable for high speed digital implementation, and are very well suited to dealing with functions with discontinuities. The nonlinear functions identified by this method can be used in a nonlinear plant Walsh function control scheme, which is currently the subject of research. A set of typical implementation results of both identification and control is included which show the efficacy of the method.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122612188","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}
