It consists of employing, in an interactive fashion, a microcomputer-based system to both drive and sample the output of a physical system in which some parameter is being varied. The microcomputer is then used to calculate and output an appropriate performance index, thereby directing the manner in which the parameter is varied, ultimately resulting in the determination of the parameter value that optimizes the performance index. Advantages of such an approach, made practical by the advent of low cost microcomputer systems, include its conceptual simplicity, the fact that mathematical models of the physical system are unnecessary, and the applicability of the approach in a manufacturing environment. To demonstrate the technique, a sample microcomputer-based system implemented by the authors is discussed along with an example in which a parameter (resistor value) in an electrical circuit is successfully optimized.","PeriodicalId":109541,"journal":{"name":"IEEE Transactions on Industrial Electronics and Control Instrumentation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124689594","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 system has a dial-in capability permitting the caller to select any one of ten messages he may wish to hear. In addition, all recorded messages are played to the caller as rate-altered or time compressed speech (rate of transmission is changed from that produced by the speaker). The speech rate may be selected independently for each tape recorder, ranging from normal (1.0) to 1.7 times the normal speed. The combination of rate-altered speech and user-interactive capability permits this system to be very efficient for many information dissemination tasks.","PeriodicalId":109541,"journal":{"name":"IEEE Transactions on Industrial Electronics and Control Instrumentation","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133399794","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}

Although various types of motors are available, all of them are not suitable. Limitations of ac synchronous motors and brushes and commutators of conventional dc motors are given. Brushless dc motors and stepper motors, which are widely used, are discussed in detail. Problems of conventional lubrication and bearings and the advantages of magnetic bearings are also discussed. In a totally noncontacting system, such as a brushless dc motor/stepper motor with magnetic bearing, life and reliability are functions of only electronic components, and they can be improved to the desired level. Thus this paper gives the problems and prospects of electric motors for space applications.","PeriodicalId":109541,"journal":{"name":"IEEE Transactions on Industrial Electronics and Control Instrumentation","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131401106","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 nondissipatively controlled, nonlinear resonant oscillator is used to extract electric energy directly from the phase pairs of the polyphase supply line and to generate a mixed amplitude-and frequency-modulated carrier. The demodulated carrier and the resulting 20-kHz pulse train produces, after being processed by a high-frequency filter, an active, low-frequency filtering effect for attenuation of the 360-Hz ripple of the apparently ``rectified'' three-phase supply line. The system is governed by means of a pulse area control mechanism with a verified response time of one 10-kHz cycle, or 100 µs. The customary dc link between the three-phase line and the converter's 20-kHz pulse-processing mechanism in the form of a common rectifier-filter is completely eliminated. Data obtained from the test of a 3-kW feasibility model are analyzed in support of the presentation of the significant aspects of design and technology.","PeriodicalId":109541,"journal":{"name":"IEEE Transactions on Industrial Electronics and Control Instrumentation","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127142908","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}
