Guaranteed cost control of networked control systems with send-on-delta transmission method

This paper is concerned with the guaranteed cost controller design for uncertain networked control systems with communication constrain. Under the send-on-delta (SOD) transmission method at sensor, the unimportant information occupancy to network resource is reduced and the system model is obtained. The sufficient condition for existence of the guaranteed cost controller under output feedback is given in terms of Lyapunov stability theory. Moreover, the parameters of the controller are determined by using LMI. At last, a numerical example is given to verify the effectiveness of the result presented in this paper.
