In order to deal with the torque pulsation problem of the PM synchronous motor in the low-speed region, new torque estimation and control techniques are proposed. The linkage flux of the PM synchronous motor is estimated using a model reference adaptive control system technique and the developed torque of the motor is instantaneously controlled by a torque controller combining variable structure control with space vector PWM. The proposed control scheme provides the advantage of reducing the torque pulsation caused by the nonsinusoidal flux distribution of the motor. This control strategy is applied to a high torque PM synchronous motor drive system for direct drive applications and implemented by using a software of the DSP TMS320C30. Computer simulations and experiments are carried out for this system and the results demonstrate well the effectiveness of the proposed control strategy.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123169859","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}

As far as voltage-mode control is concerned, a novel multi-loop control allows synthesis of the desired regulator transfer function by using only low-pass filters, thus reducing the high-frequency noise coupling typical of standard PID regulators and reducing the dependency of crossover frequency and phase margin on output capacitor ESR. In the paper, useful design considerations are given and verified with an experimental prototype.","PeriodicalId":423659,"journal":{"name":"Proceedings of APEC 97 - Applied Power Electronics Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115272054","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}

They are used from simple applications like camera flashes to extremely demanding ones such as photometry, chemical analysis, spectroscopy, etc. A power supply to drive a xenon lamp must provide a substantially high voltage and current, and must provide a controlled high voltage pulse to strike the arc.
