【Abstract】 Based on the equivalent representation of interval matrixes, the nonlinear time-varying stability problem of fuzzy control system has been converted into the robust stability problem of linear system with time-varying uncertainty. Using the control law of maximum membership, a necessary and sufficient condition for the quadratic stability of T-S fuzzy system is given. Simulation results show the effectiveness and advantages of the proposed method.更多还原
