Adaptive stabilization control of non-smooth-air-gap PMSM chaotic systems with uncertain parameters

This paper considers the stabilization control problem of the non-smooth-air-gap permanent magnet synchronous motor (PMSM) chaotic systems with uncertain parameters. Based on the adaptive theory, a novel adaptive feedback controller is designed to stabilize the uncertain PMSM chaotic system to the zero equilibrium asymptotically. The asymptotic stability of the controlled PMSM chaotic system is proved based on Lyapunov stability theory. Simulation results demonstrate that the designed adaptive controller can stabilize the uncertain PMSM chaotic system successfully.
