It is very meaningful to study the robustness of the control technology for PMSM drive system used in electric vehicle. Firstly，according to the application requirements of the electric vehicles, interior permanent magnet synchronous motor (IPMSM) is selected as the research object. Summarizes the structure and the mathematical model of permanent magnet synchronous motor. Secondly, aim at demanding of the higher requirement of speed dynamic response in the control system of permanent magnet synchronous motor, analysesed the system of the conventional PI speed controller for the fuzzy controller . Thirdly, analysesed the robustness of the control system of permanent magnet synchronous motor, on the basis of the maximum torque per amper (MTPA)control. Finally, analysesed the robustness in current loop of the control system of the permanent magnet synchronous motor to external disturbance such as load change.
