Abstract: In this paper, we deal with the stochastic stability of uncertain hybrid linear systems with Markovian jumping parameters and time delay. Under the assumption of mismatched boundedness of system′s uncertainties, sufficient conditions that guarantee asymptotic stability with probability 1 of the system are given, then a parameter adaptive estimation and robust adaptive control law are proposed for unknown upper bounds on the norm of uncertainties that guarantee the asymptotic stability with probability 1 for matched uncertain hybrid systems. The results show that this adaptive control method is useful for uncertain hybrid linear systems with time-delay. -
