英文摘要 |
The stabilization problem is addressed for a class of switching fuzzy time-delay systems. For the nonmeasurable states, a switching fuzzy observer and a feedback controller are designed based on the parallel distributed compensation(PDC) method. Asymptotic stability of the observed error system is then obtained by the common-Lyapunovfunction method. A switching law is also designed by the multiple-Lyapunov-function method to guarantee the asymptotic stability of the systems. Delay-dependent conditions for asymptotic stability of the switching fuzzy systems are obtained in terms of matrix inequalities. Finally, simulation results show effectiveness of the design method. |
