Abstract

Based on the common Lyapunov function method, a model reference control method for uncertain switched systems is presented. Firstly, a reference switched system and the relative switched controller are respectively designed. Afterward, via the common Lyapunov function method, a sufficient condition that guarantees the closed-loop switched system being uniformly bounded is deduced. Finally, the proposed method is applied to control a servo-hydraulic system, the reference switched system and switched controller are given for the servo-hydraulic system on different supply pressure. Simulation results show that the desired control precision is acquired by the proposed method.
