Finite-Time Composite Antidisturbance Control for T-S Fuzzy Nonhomogeneous Markovian Jump Systems via Asynchronous Disturbance Observer

This article studies the finite-time composite antidisturbance control problem for non homogeneous Markovian jump systems (MJSs) subject to multiple disturbances via the Takagi-Sugeno (TS) fuzzy control scheme. The designed two-gains disturbance observer (Wand the considered MJSs are supposed to switch the different Markovian chains, which are depicted by a hidden Markovian model. Herein, an asynchronous DO design is explored for the first time, providing new insight into the construction of asynchronous DO. First, the H-infinity/L-2 - L-infinity finite-time boundedness of the augmented system is guaranteed. Second, bused on the Finsler lemma, the linearization issue in calculating observer/controller gain is addressed. Finally, two illustrations are presented to verify the effectiveness of the proposed method.
