| Research Abstract |
Recently, much attention has been attracted for system identification, stimulated by develepment of robust control theory in the presence of model uncertainty. Considerable improvement of estimation accuracy is expected because processing in smaller sampling period has become possible due to the progress of the technology around microcomputer. We have studied mainly from the viewpoint of
(1) effects of prefileter suce as antialias filter to system identification
(2) development of the method to determine the order of a model
(3) evaluation of system identification methods for robust control
(4) extension to multivariate systems, and
(5) development of methods for nonlinear systems.
Our intention has been development of identification scheme suited well for controller design, from standpoint that the quality of the model depends on that the model has capability to trace adequately the characteristics in proper frequency range, and that prefilter is not only data processing but also ones taking a priori knowledge of the plant into the model. We showed totally in this research, that the identification schemes can be applied to large scale, complex real systems by extending them to multivariate systems and developing nonlinear systems identification, taking account of physical information of the plant.
