Abstract :
State feedback control problem for a class of switched linear systems and its application are studied. Based on switched Lyapunov function and some basic lemmas, the purpose is to design a switched state-feedback controller with a switching scheme guaranteeing the local asymptotic stability of the resulting closed-loop system. And analyze the domain of attraction by using a convex optimization problem subject to linear matrix inequalities(LMI) constraints. Finally, the method is applied to a high precision test turn-table and the simulation results show the effectiveness of the proposed method.
