Design of adaptive variable structure controllers for T-S fuzzy time-delay systems

摘要

In this paper, the adaptive variable structure control problem is presented for Takagi-Sugeno (T-S) fuzzy time-delay systems with uncertainties and external disturbances. The fuzzy sliding surfaces for the T-S fuzzy time-delay system are proposed by using a Lyapunov function, and we design the adaptive variable structure controllers such that the global T-S fuzzy time-delay system confined on the fuzzy sliding surfaces is asymptotically stable. One example is given to illustrate the effectiveness of our proposed methods.
