The stabilization of switched nonlinear systems with pre-specified average dwell time is studied in this paper. An approach to controllers design using control Lyapunov function is proposed, the proposed switched controllers can stabilize the switched nonlinear systems with the pre-specified average dwell time. Furthermore, if there exists disturbances in switched systems, the proposed approach can be extended to design robust switched controllers which can guarantee the input-state stability of the switched nonlinear systems to disturbances. Finally, the simulations show the effectiveness of the approach proposed in this paper.
