The tasks can be configurated and parametrised either with a sequence of commands in a menu driven way or, graphically, in a WINDOWS oriented way. The extensive function block library contains many different function blocks for conventional and modern control-algorithms. The function blocks that are needed to configurate tasks for sequence-control and those which are needed for identification, filtering and process I/O are available as well. The performance of a control-unit is also assessed by comparing the control-unit communicates with the other approaches. We show that it is possible to reduce significantly the needed calculating time for sequence-control tasks if a real-time management is used, which allows a periodic scheduling as well as an aperiodic scheduling. We also demonstrate that, if a complex sequence-control algorithm is divided up into small synchronised parts, it is possible to reduce the calculating time even more.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115776216","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}

Two capabilities of neuro-controllers are demonstrated using a nonlinear model of the Space Station Freedom. These capabilities are: 1) synthesis of robust nonlinear controllers using neural networks; and 2) adaptively modifying neuro-controller characteristics for varying inertia characteristics. The main components of the adaptive neuro-controllers include an identification network and a controller network. Both these networks are trained using the backpropagation of error learning paradigm. To ensure robustness of the neuro-controller, an optimally connected neural network is synthesized for the identification network. For the online adaptive control problem, a new technique using a memory filter for error backpropagation is introduced. The performances of the nonlinear neuro-controllers for cases listed above are verified using a nonlinear simulation of the Space Station. Results presented substantiate the feasibility of using neural networks in robust nonlinear adaptive control of spacecraft.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115536817","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}
