摘要

A new robust fractional order sliding mode controller (FOSMC) is proposed for the position control of a permanent magnet synchronous motor (PMSM). The sliding mode controller (SMC), which is insensitive to uncertainties and load disturbance, is studied widely in the application of PMSM drive. In the existing SMC method, the sliding surface is usually designed based on the integer order integration or differentiation of the state variables, while in this proposed robust FOSMC algorithm, the sliding surface is designed based on the fractional order calculus of the state variables. In fact, the conventional SMC method can be seen as a special case of the proposed FOSMC method. The performance and robustness of the proposed method are tested for nonlinear load torque disturbance, and simulation results show that the proposed algorithm is more robust and effective than the conventional SMC method.
