Abstract:
Based on common Lyapunov function approach and convex combination technique,the sufficient condition for the existence of sub-controllers is presented,which is in the form of matrix inequalities.Both sub-controllers and switching rules are designed.By using eliminated element method,the matrix inequalities are changed into linear matrix inequalities.A numerical example is employed to illustrate the validity of the results.The results indicate that the closed loop system satisfies the robust H∞ performance at each point in whole state-space through switching,although each sub-system doesn’t satisfy the performance and even is not asymptotically stable.
