Solutions obtained by this method may in general be any kind of connection with any number of contacts for each variable. Furthermore, any practical requirements such as series-parallel cases usually found in most electronic devices, and single contact for specified variables, can all be considered in the calculation, if necessary. A routine algorithm on incidence matrices will automatically yield any ingenious connections. The node-branch and branch loop incidence matrices which were revealed by G. R. Kirchhoff 1847, are adopted as unknown, especially those of modulo 2 which were elaborated by O. Veblen in 1916 are mostly used. However, simultaneous use of modulo zero (or infinity), 2 and other integers was found useful for combinatorial consideration in the multi-contact case. General Galois fields are already used in switching theory by Moisil and his Rumanian group.","PeriodicalId":281900,"journal":{"name":"IRE-AIEE-ACM '59 (Eastern)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1959-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133285698","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 procedure usually followed is to determine a control-system configuration by simplified analysis and then to program a computer in a realistic way, including all significant nonlinearities and appropriate random input disturbances. Next, a performance criterion of some sort is selected for the control system under study, and system parameters (gains, time constants, etc.) are varied until an optimum system is obtained. At this point, simulation activity usually ceases and is not resumed again unless the actual control system either cannot be constructed to obtain the desired parameter values or else fails to attain the level of performance indicated by the earlier simulation.","PeriodicalId":281900,"journal":{"name":"IRE-AIEE-ACM '59 (Eastern)","volume":"337 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1959-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122538574","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}
