Observer-based networked control for continuous-time systems with random sensor delays

This paper is concerned with the networked control system design for continuoustime systems with random measurement, where the measurement channel is assumed to subject to random sensor-delay. A design scheme for the observer-based output feedback controller is proposed to render the closed-loop networked system exponentially mean-square stable with H∞ performance requirement. The technique employed is based on appropriate delay systems approach combined with a matrix variable decoupling technique. The design method is fulfilled through solving linear matrix inequalities. A numerical example is used to verify the effectiveness and the merits of the present results.
