Chaos anti-control of PMSM based on exact linearization via delay-time state variable feedback

The conditions of exact linearization of controlling permanent-magnet synchronous motor are discussed with differential geometry method based on mathematic model. We completed permanent-magnet synchronous motor linearization in the entire state variable space. Applying the analysis results, we designed the time delayed state feedback chaos controller and the control results are studied by simulation method. Different control parameters may conduct different results, so we simulate the influence of the controlled variable on the anti-control of chaos, cleared about the controlled variable choice. The simulation results show that the time delayed state variable feedback method which using differential geometry theory design chaos anti-controller to realize chaotification on permanent-magnet synchronous motor model is feasible and the control result is satisfing.
