Hamerlain","doi":"10.1109/ISIC.1995.525069","DOIUrl":"https://doi.org/10.1109/ISIC.1995.525069","url":null,"abstract":"The variable structure control (VSC) is based on switching functions of the state variables used to create a \"sliding mode\". The purpose is to force the system dynamics to correspond to the one defined by the surface equation. When the state is maintained on this surface, the system dynamics become insensitive to parameter variations of the plant, and to unmodeled nonlinearities. This paper is the follow up work on the controller design for two axis robot arm using a variable structure model reference adaptive controller. It addresses the design of sliding mode controllers for perturbed systems characterized by the presence of the switching element imperfections (delay, small time constants, and the unmodeled dynamics). It is shown that its specific reaching conditions are satisfied for the reduced-order models and an additional condition is met, then the reaching conditions are also satisfied for the full-order model (take into account unmodeled dynamics, small time constants, switching delays, etc.). In this note the sliding mode control law is considered for the reduced-order model, and a composite control is implemented on the full-order model. Further, in sliding mode the controller system design can be reduced into a lower-order and free system. Advantages of such a control law appear from the following viewpoints: methodology-the control law can be easily implemented in an online computer as a classical control law (PID, RST...); robustness to unmodeled dynamics (the plant dimension is higher than the one of the model); quality of tracking trajectory.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128750762","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 this paper we examine the model of a tactile pad sensor, assumed to be a finite dimension medium. The model of the tactile pad sensor is obtained using an integral relation between the boundary conditions and the stress tensor. A set of stress sensors is allocated in the tactile pad, the model is discretized and a direct relation between the parameters of the shape to be recognized and the measured stress is obtained. Due to the ill-posedness of the problem, classical least squares estimation and regularized estimation are examined. Numerical simulations in order to evaluate the inversion technique with different shapes of the object, are presented.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116802587","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 authors introduce the concept of the hypothesis objects, and augment the production rule format by adding the hypothesis condition elements in the LHS part of a rule, which control the forward and backward chaining invocation of rules. To be applied to the backward chaining, a modified version of the Rete network has been formulated by adding the hypothesis-and-nodes and backward direction edges to the node network generated by the Rete algorithm. The authors then develop a backward chaining algorithm which takes advantage of already existing partial match results obtained by the previous forward chaining. The forward and backward chaining can be naturally integrated via the generation of hypotheses from forward chaining inference. The whole mixed inference process has the potential advantages over purely forward and backward chaining strategy.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131025561","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 assumed that the controllers apply an adaptive method to achieve the optimal result. The optimization is challenging since the controllers have delayed information concerning the individual elements of the control vector. The potential exists for each element to be viewed with its own unique delay. Linear stability analysis provides an upper bound of the conditions for damped oscillations and a lower bound on the conditions for persistent oscillations. The results indicate that controllers can improve performance with respect to stability by: 1) communicating more frequently, 2) interacting in smaller groups, 3) slowing down the adaptive search process, and 4) creating more diversity in the delays.","PeriodicalId":219623,"journal":{"name":"Proceedings of Tenth International Symposium on Intelligent Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131246868","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}
