Chaotic control of permanent magnet synchronous motor based on washout filter technique

A chaos control method is presented in the paper for the permanent magnet synchronous motor （PMSM）, which uses the current of the PMSM as its feedback based on washout filter technique. Only the parameter of the filter is needed and no parameter of the original system will be affected by using the controller. Simulation result presents the simplicity, effectiveness and robustness of the method.
