Guaranteed cost fault tolerant controller design for nonlinear networked control systems

This paper is concerned with the state feed-back guaranteed cost fault tolerant control of networked control systems with both network-induces delay and data dropout. Using LMI approach, The sufficient condition for the existence of the networked guaranteed quadratic cost controller is obtained in terms of matrix inequalities, and the controller design method is deduced in terms of linear matrix inequalities. Furthermore, the suboptimal networked guaranteed cost controller design method is obtained with cone complementarity linearization algorithm. A numerical example is given to illustrate the proposed method.
