Application of Adaptive Fuzzy Sliding Mode Controller in PMSM Servo System

摘要

An adaptive fuzzy sliding mode controller is presented for a nonlinear system with perturbed uncertainties of PMSM (Permanent Magnet Synchronous Motor) associated with the sliding mode control. This controller employs fuzzy control to assign compensate according to expert's experience, and adaptive control to attenuate chattering caused by sliding mode control. This method is applied to PMSM servo system's position control. Both simulations and experiment results verify the validity and robustness against uncertainties of load disturbance.
