This paper addresses the problem of disturbance attenuation and rejection for discrete-time Markovian jump systems with lossy measurements and multiple disturbances.The measurement transmission from the plant to the observer and the controller are assumed to be imperfect and two stochastic variables are utilized to model the phenomenon of data missing,separately.Composite DOBC(Disturbance-Observer-Based Control)& H∞ control is proposed to attenuate and reject the disturbances,simultaneously.Our attention is focused on the design of a new structure of disturbance observer,dynamic output feedback controller,and composite controller such that the composite system is stochastically stable and satisfies some scheduled performances.Computation oriented conditions on the disturbance observer gain,and controller matrices for the controlled plant are provided based on the piecewise quadratic Lyapunov functions..
