The filter measures the spectral densities of the input signal and noise processes and adjusts its band-pass to give optimal filtering in the Wiener sense. The behavior is examined in the linear approximation and a crude treatment of the nonlinear transient response is given. These results compare favorably with an analog simulation.","PeriodicalId":226447,"journal":{"name":"Ire Transactions on Automatic Control","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126733007","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 model in which a group of components is commutated sequentially around several control loops is presented. Two mathematical procedures, borrowed from known sampled data and state-space techniques, permit the detailed analysis of the resulting linear system. It is seen that timesharing creates cross coupling or interaction between control loops which are independent except for the shared component. There is no cross coupling in the steady state if each loop contains at least one integrator. It is concluded that timesharing is an economic proposition in which possible savings in equipment cost are balanced out against reduced system performance.","PeriodicalId":226447,"journal":{"name":"Ire Transactions on Automatic Control","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117040973","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}

In exacting feedback problems where the parameter variations or disturbances are large, the resulting single-loop transmission may require a larger gain and bandwidth than that of the plant. The added feedback compensation networks then have rising frequency characteristics and make the system very sensitive to HF noise in the feedback path. It is shown how a multiple-loop design permits the attainment of the same benefits of feedback, but with considerably less sensitivity to the HF noise. The basic problem is how to divide up the feedback burden most efficiently among the various loop transmission functions. Detailed procedures for this purpose are presented in the paper. The treatment is restricted to cascade-type plants.","PeriodicalId":226447,"journal":{"name":"Ire Transactions on Automatic Control","volume":"74 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120823752","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}

Convergence-time relationships and sufficient conditions for system stability are developed when the process is characterized by a variable gain or variable time-constant, and fixed dynamics of any order. The adaptive capability is achieved by employing a model as a reference element and by means of appropriate adaptive circuitry. The adaptive circuitry is simple, easily instrumented, and does not require successive differentiations; the primary function of the adaptive circuitry is one of integration.","PeriodicalId":226447,"journal":{"name":"Ire Transactions on Automatic Control","volume":"421 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":"123096181","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}
