Abstract-The problem of H∞ stability analysis and cont rol synthesis of switched systems with delayed states under arbitrary switching laws is considered. By means of Lyapunov function and linear matrix inequality t ools, sufficient condition of H∞ stability is presented in terms of lin ear matrix inequalities. Furthermore, the robust H∞ control synthesis via state feedback and output feedback is studied. Finally, a numerical example is given to demonstrate the effectiveness of the proposed method.
Key words-time-delay switched systems; H∞ perfo rmance; Lyapunov function; linear matrix inequality
