Abstract :
The fuzzy sliding mode control strategy was designed in this paper based on the SVPWM-DTC method, which can be used in the PMSM-AMT structure of electric vehicle drive system. The PMSM torque dynamic and steady control is analyzed in the strategy. The sliding mode control switching function and the sliding surface of PMSM torque closed-loop were also discussed. And the chattering problem was weakened by the method of fuzzy. The simulation and experimental comparison verified the validity of the control strategy.
