Chaos Analysis and Control of Permanent Magnet Synchronous Motors
As a nonlinear dynamic system, the permanent magnet synchronous motor (PMSM) can exhibit prominent chaotic characteristics under some choices of system parameters. The existence of chaotic attractor of the PMSM is verified through the centre manifold theory and Poincaré section. Chaotic phenomenon affects the normal operation of motor. In this paper, it makes the PMSM in a stable state to control chaos of the PMSM with a control strategy of delay feedback, which can eliminate chaos well.
