Abstract:

In order to overcome the chattering existing in the conventional first-order sliding mode controller and the static error resulting from the fuzzy control system,a fuzzy fractional-order sliding mode controller,which integrates the advantages of sliding mode control and fuzzy control and makes use of fractional-order differential and integral calculus,is proposed for the velocity control of permanent magnet synchronous motor. Then,the design method of the controller is presented and the performance of the controller is analyzed. Simulated and experimental results indicate that the proposed controller possesses high control performance and strong robustness to external load disturbance.

Key words: permanent magnet synchronous motor, fractional order, sliding mode control, fuzzy control, chattering, robustness
