Chaos anti-control of permanent magnet synchronous motor based on model matching

The method of chaos anti-control for permanent- magnet synchronous motor (PMSM) is proposed by using model matching and time delayed state feedback. The PMSM chaotic restrictions were discussed with model matching theory based on mathematic model. Chaotic reference model was produced using stable linear system by time-delay feedback sinusoidal function. Then match controlled system that can´t exact linearization globally to the chaotic model. This chaotification method was easily to adjust the reference model degrees according to different controlled system. The simulation results show that the proposed method that using differential geometry theory design chaos anti- controller to realize chaotification on PMSM model is feasible and the control result is satisfied.
