Approaches to Robust Filtering Design of Discrete Time Fuzzy Dynamic Systems
Gang Feng, Meng Chen, Dong Bai Sun, Tiejun Zhang · IEEE Transactions on Fuzzy Systems · 2008
This paper presents two filter design methods for discrete time fuzzy dynamic systems based on a piecewise quadratic Lyapunov function. It is shown that the resulting filtering error system is globally stable with guaranteed Hinfinor generalized H2performance and the filter gains can be obtained by solving a set of linear matrix inequalities. Two simulation examples are also given to illustrate the performance of the proposed approaches.
