Robust fuzzy control for permanent magnet synchronous motor chaotic systems with uncertain parameters

This paper is concerned with the robust control problem of the permanent magnet synchronous motor (PMSM) chaotic systems with uncertain parameters. Firstly, the T-S fuzzy models with several fuzzy IF-THEN rules are employed to represent the uncertain chaotic PMSM plant. Based on these the T-S fuzzy models, a simple fuzzy controller is designed via PDC technique to realize the stabilization of chaos. The robust stability of the closed-loop chaotic PMSM systems are proved based on Lyapunov stability theory. The controller gains are derived by solving a set of LMIs. Simulation results demonstrate that the designed fuzzy controller can stabilize the uncertain chaotic PMSM systems with rapid response.
