With the progress and development of society, the new energy automobile is a necessary way for China""s automobile industry to become stronger，which is one of the effective ways to solve the environmental problems and energy crisis. Permanent magnet synchronous motor (PMSM) is the most common driving motor in electric vehicles, and its robustness is especially important for the driving performance of the whole electric vehicle. In order to better meet the drive performance of electric vehicles, this paper proposed a new adaptive fuzzy sliding mode control method, which optimized the current robustness and buffeting of permanent magnet synchronous motor. This method combined the fast terminal synovial control theory with fuzzy control theory, which not only realizes the dynamic adjustment of the sliding mode gain, improved the robustness and stability of the system obviously, but also improved the control precision of the current and the response speed effectively. Simulation results show that the method is effective.
