Design of Output Feedback Controller for Networked Control Systems with Delay and Packet Dropout

Abstract

The design problem of controller for a dynamic output feedback networked control system with uncertain short time delay and packet dropout is studied. The data packet dropout is assumed to be satisfied with the Bernoulli distribution sequence with known probability. The dynamic output feedback networked control system is modeled as a discrete time-varying system with uncertainties. Sufficient conditions for the existence of the controller are given by the linear matrix inequality (LMI) method and the Lyapunov principle. And the controller design problem is transformed into solving the feasible solution of LMI. Finally, a simulation example is given to prove the effectiveness and feasibility of the design method.
