Less Conservativeℋ∞Fuzzy Control for Discrete-Time Takagi-Sugeno Systems

摘要

New analysis and control design conditions of discrete-time fuzzy systems are proposed. Using fuzzy Lyapunov's functions and introducing slack variables, less conservative conditions are obtained. The controller guarantees system stabilization andℋ∞performance. Numerical tests and a practical experiment in Chua's circuit are presented to show the effectiveness.
