A step-by-step description of the method is given as it was applied to the problem of determining an optimal startup sequence for a satellite power plant. In the present case the criterion of optimality is the amount of auxiliary energy required for the startup of the power plant in orbit. A phase space is defined in terms of pertinent power plant variables; the solution is then obtained by treating the problem as aa N -stage decision problem consisting of selecting a sequence of phase space points such that the path so traced between the point representing the initial state of the plant and the point representing the final, operating state satisfies the criterion of optimality. Numerical calculations were performed with the aid of the digital code described in the Appendix. The results of this parametric study indicate possible energy savings up to 25 per cent. The paper is self-contained in the sense that very little if any contact with reactor technology or dynamic programming is required by the reader.","PeriodicalId":226447,"journal":{"name":"Ire Transactions on Automatic Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128926977","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 importance of new ideas in this field using progress in automatic control theory is stressed. The most importemt feature of the new hand is the two level control. The movements of the hand can be controlled by signals produced by man as well as by external stimuli. For this purpose simple pressure sensitive transducers are placed in the hand to provide the control signals for reflexive-type movements. An adaptive control circuit is present for automatic weight adjustment. All these features are incorporated into the hand using simple and standard servocomponents. Use of appropriate feedback loops eliminates the need for complicated mechanical parts.","PeriodicalId":226447,"journal":{"name":"Ire Transactions on Automatic Control","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125518893","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 transfer function of the model is the inverse of the desired transfer function of the closed-loop system insofar as it is practically realizable. Proper operation is obtained by adjusting the system until the poles of the closed-loop system are canceled by the zeros of the model. Special filters are designed to aid in the detection of this cancellation. They have a narrow pulse for an impulse response and the dispersion of this pulse is used as the measure of error when an impulse is applied to the system. The criterion used for the design of the filter is that its impulse response should have a minimum second moment about the time of the maximum. The technique is applied to a fourth-order pitch-rate control system and the results of the computer simulation are given.","PeriodicalId":226447,"journal":{"name":"Ire Transactions on Automatic Control","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130056624","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}
