Adaptive Sliding Mode Variable Structure Control of Chaos in Permanent Magnet Synchronous Motor

Permanent magnet synchronous motor(PMSM), Chaotic system, Adaptive sliding mode control

This paper proposes a robust adaptive sliding mode control strategy aiming at the complex chaotic behavior of permanent magnet synchronous motor（PMSM）. Using the sliding mode control technique, a time varying surface is constructed. Then an adaptive gain of the robust control law is established considering uncertainties and external interference in PMSM. So the phenomenon of chaos in PMSM system will be eliminated using proposed controller. Finally, stability analysis will be given based on Lyapunov stability theory. Simulation results demonstrate the effectiveness of the proposed adaptive sliding mode control scheme.
