The measurement process is in two parts. First, the microprocessor measures the voltage waveform period and computes the sampling interval and number of samples. The measurement of average power then takes place over an integer number of cycles. Digitized samples of the voltage and current waveforms are multiplied together and the products accumulated over the measurement period. The sum is divided by the number of samples, scaled, and read out as a 4-digit display of average power.","PeriodicalId":109541,"journal":{"name":"IEEE Transactions on Industrial Electronics and Control Instrumentation","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129876160","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}

It is shown that the maximum allowable gain of the error amplifier is a function of the modulation process, the duty cycle of the switch, and the filter elements of the supply. Under certain conditions, the gain can be made infinitely large. This can occur for duty cycles less than 50 percent if the end of the ``on'' time is modulated and for duty cycles between 50 and 100 percent if the start of the ``on'' time is modulated. Excellent agreement with computer simulations and laboratory measurements has been observed.","PeriodicalId":109541,"journal":{"name":"IEEE Transactions on Industrial Electronics and Control Instrumentation","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128821158","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}

When a microcomputer is used to perform the control algorithm and to monitor the motor speed, the sampling rate and the controller parameters must be chosen so that the sampled-data system is stable. In this paper, two typical motor control systems are studied; one is based on frequency comparison, and the other on the use of a phase-locked loop. The result shows that the sampling period has a stable region when the system constants and the controller parameters are given. The paper also reveals the information for determining the measuring time and the controller parameters.","PeriodicalId":109541,"journal":{"name":"IEEE Transactions on Industrial Electronics and Control Instrumentation","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125583526","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}

Three methods of transient analysis are derived for TRC control and compared with regard to accuracy and usefulness. The methods require much less computation time than is necessary for a step-by-step solution of the system differential equations, for different intervals of the chopper cycle. Two of the methods can be used for deriving transfer functions of the time-ratio chopper-controlled de series motor for small-signal perturbations around a steady-state point.","PeriodicalId":109541,"journal":{"name":"IEEE Transactions on Industrial Electronics and Control Instrumentation","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123906823","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}
