Robust Fuzzy Observer Design for Nonlinear Systems

Authors: C. Ardil, Michal Polanský


This paper shows a new method for design of fuzzy observers for Takagi-Sugeno systems. The method is based on Linear matrix inequalities (LMIs) and it allows to insert H constraint into the design procedure. The speed of estimation can tuned be specification of a decay rate of the observer closed loop system. We discuss here also the influence of parametric uncertainties at the output control system stability.

Keywords: Observers, linear matrix inequalities, H norm, Takagi-Sugeno Systems, Parallel Distributed Compensation
