Abstract:

Based on the robust control theory, the problem of passive control and the design of  the observer-based passive controller for a class of nonlinear uncertain time-delay Markov jump systems are dealt with by using linear matrix inequalities. By constructing proper Lyapunov functions, a sufficient condition for the system to be asymptotically stable with a passive index bound is presented for all admissible uncertainties, time-delays,
and nonlinearities. The passive controller is obtained by solving a linear matrix inequality. Simulation results demonstrate the validity of the proposed approaches.
