Design of fuzzy control system with robust pole placement constraints
鲁棒极点配置约束下的模糊控制系统设计

A method of designing fuzzy controllers and fuzzy state observers with robust pole placement constraints for a class of uncertain nonlinear systems approximatively expressed by Takagi-Sugeno(T-S) fuzzy dynamic model was proposed.Firstly,based on the concept of the prallel distributed compensation(PDC) and the theory of robust pole placement,a sufficient condition which guarantees global asymptotic stability of the whole system and satisfies desired performance was obtained.Then,the condition was converted to a standard linear matrix inequalities(LMI) problem in the design procedures.Finally,the simulation of an inverted pendulum verified the effectiveness of the design method.
