| This paper is based on previous research results on fuzzy control systems. First, the robust covariance control and stability problem for a class of fuzzy systems with time varying, but norm-bounded parametric uncertainties is considered. Then, robust stabilization and control of a class of uncertain discrete-time systems with time delay described by T-S fuzzy models is introduced, and robust H controller design problem for a class of stochastic uncertain discrete-time fuzzy systems with time delay is analyzed. By using linear matrix inequality (LMI) approach, the sufficient conditions of robust stability for closed-loop fuzzy systems and the corresponding controllers design method are presented. Finally, the prospect of fuzzy systems and some issues, which should be solved are pointed out in this paper. |
