An H<inf>¿</inf> control design approach to networked control systems

This paper is concerned with the design problem of robust H∞ control for linear networked control systems (NCSs) with network-induced delay and data packet dropout.By choosing a new Lyapunov-Krasovskii functional, a sufficient condition on the existence of robust H∞ controller is derived in the form of a matrix inequality.No model transformation is needed and no redundant matrix variable is introduced.Then an iterative algorithm is introduced for obtaining the robust H∞ controller design method based on the matrix inequality.No parameter needs to be selected in advance.Two numerical examples are finally given to illustrate the effectiveness of the proposed algorithm.
