摘要：

In order to enhance the disturbance attenuation of the permanent magnet synchronous motor (PMSM) servo system, an adaptive sliding mode controller based on maximum torque per ampere (MTPA) control is designed in the paper. The MTPA control is used to obtain the d; q-axes currents, and the sliding mode control is used to enhance the disturbance attenuation of the system, but the chattering is also brought to the system. In addition, an improved adaptive sliding mode reaching law is designed for the position control to attenuate the chattering. Furthermore, the polynomial curve fitting method is adopted in the MTPA control which strengthens the practicability of the controller. The simulation results show that the proposed controller not only enhances system dynamic, static performances and robustness, but also attenuates the chattering caused by sliding mode control. ©, 2015, South China University of Technology.
