Abstract�� When the moment of inertia becomes big, huge inertia torque will be produced when the directly drive permanent magnet synchronous motor(PMSM) system starts, stops or changes speed, thus to bring impact on the system performance. In order to solve this kind of problem, the control method on the sliding mode variable structure was adopted. The mathematic model of the PMSM was established and the factor of friction was considered. And the sliding mode variable structure controller was designed. The Simplorer simulation system of Ansoft Company was used to simulate the whole system. Then a comparison was made between the performance of proportion-integral (PI) control and sliding mode variable structure control. The results show that the sliding mode variable structure controller method can be adapted to the moment of inertia loading control system.
