Iterative system identification and controller design with an LMI-based framework: Windsurfer-like approach

An lmi-based method for the integrated system identification and controller design is proposed in the paper. we use the fact that a class of a system identification problem results in an lmi optimization problem. by combining lmis for the system identification and those to obtain a discrete time controller we propose a framework to integrate two steps for the model-based control system design,that is,the system identification and the controller synthesis. the framework enables us to obtain a good model for control and a model-based feedback controller simultaneously in the sense of the closed-loop performance. an iterative design algorithm similar to so-called windsurfer approach is presented. © 2012 kazuhiko hiramoto.
