While disk drives in personal computers only a few years ago had capacities of a few hundred megabytes, storage capacities of an order of magnitude greater are increasingly commonplace. The disk drive essentially consists of one or more disks which store the data, spinning at a high rotational speed, usually of the order of a few thousand revolutions minute (RPM). An actuator which supports suspension for the data accessing heads moves over the data surfaces of the disk(s) and transfers data to and from the other parts of a computer. Since, based on capacity, the number of data disks can vary from one to ten (or even higher), and the rotational speed can vary over a wide range, the spindle motors used in these disk drives can be of very different designs.","PeriodicalId":126938,"journal":{"name":"5th IEEE Workshop on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114530291","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 operating-mode boundaries are obtained by tracing the solution curves by using the concept of the homotopy continuation method.","PeriodicalId":126938,"journal":{"name":"5th IEEE Workshop on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114984424","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}

By controlling both the phase displacement angle and voltage amplitude, the performance of the conversion system is improved compared with the traditional power angle control.

To reduce harmonics and noise, a Kalman estimator is applied to the input signals of the controller. When state equations are used, the inverter system as well as the feedback and feedforward parameters are easy to handle by using the Matlab/Simulink program.

The resulting power converter model is referred to as a transient behavioral model (TBM). First, a simple buck power converter is used to demonstrate the TBM. A power converter called the dynamic voltage restorer is used to demonstrate a practical application of the TBM. It is shown that the TBM yields simulation results almost as accurate as the ideal switch model (ISM). At the same time, the TBM is computationally more efficient than the ISM. These features, coupled with the simplicity and the ease of implementation in a standard circuit simulator, make the TBM an attractive alternative to the ISM.","PeriodicalId":126938,"journal":{"name":"5th IEEE Workshop on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124054962","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}
