Two main perspectives are considered: neurological and engineering. From the neurological perspective, the problem is described, main sensory systems are identified, sensor fusion is suggested, and control system architecture and details are presented. Experimental results on both human subjects and on a special-purpose humanoid agree with the presented architecture. On the other hand, the humanoid parameters are identified, the humanoid dynamic model is derived, external-disturbance estimation methods are presented, a control method for stabilizing the body motion and then for robust tracking of voluntary motion in the presence of external disturbances is shown. This constitutes an engineering approach to this problem. Simulation results are given and it is shown that the presented method is capable of estimating the disturbances and for controlling the motion","PeriodicalId":347035,"journal":{"name":"2006 14th Mediterranean Conference on Control and Automation","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122127039","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}

Wiener systems consist of the cascade connection of a linear time invariant system and a static nonlinearity. Several approaches were reported in the literature in order to control this kind of systems. Most of these control schemes involve a transformation of the measured variable as well as the setpoint by using the inverse of the nonlinear gain. As regards the uncertainty in the Wiener model, it is usually described as a partitioned problem. The linear block is considered as a parameter-affine-dependent model. On the other hand, the nonlinear block uncertainty is analyzed as a conic-sector. The robustness evaluation is performed using mu-theory. The results are interpreted on the basis of a simulation of a pH neutralization process","PeriodicalId":347035,"journal":{"name":"2006 14th Mediterranean Conference on Control and Automation","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122134712","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}

We consider two tracking patterns depending on the nature of the reference signal i.e: whether it is measured on line or previewed in a fixed time-interval ahead. The stochastic uncertainties appear in both the dynamic and measurement matrices of the system. For each of the above two cases a solution is found where, given a specific reference signal, the controller plays against nature which chooses the initial condition and the energy-bounded disturbance. The problems are solved by applying a special Lyapunov function which leads to an LMI based tractable solution.
