%X Robust stabilization for uncertain linear systems is studied using Lyapunov stability theory and linear matrix inequality approach. Parameter uncertainties under consideration are time-varying and norm-bounded. A sufficient condition for the existence of such a controller is established in a Q-LMI form, and the solution procedure of the Q-LMI problem is proposed. The solvability for the Q-LMI problem can be improved by adding some LMI constraints to the Q-LMI. Based on the Q-LMI condition, a robust stable layered control strategy for the robust stabilization, namely, "different controller is acted on the system with different parameter perturbation", is presented. An example is given to illustrate the feasibility of the strategy.
