In view of the flaws of poor robustness and anti-jamming performance found in permanent magnet synchronous motor (PMSM) under sudden load changes or disturbance, a proposal has been made of a fuzzy PI control speed regulation system for permanent magnet synchronous motor based on feedforward compensation. This new system, with the frictional force of the motor coupling shaft, the momentum needed by the load and the force produced by the inertia of the load as the total disturbance, seeks to establish a disturbance feedforward module so as to identify the total disturbance, and with its compensation to the speed loop, a solution can be achieved of the problem that the response speed of the motor fails to keep up with the system with the motor load changes. The simulation results show that the fuzzy PI permanent magnet synchronous speed control system, which is based on feedforward compensation, is characterized with the advantages of super anti-disturbance performance and robustness.
