Abstract :
As for the system of flexible load driven by permanent magnet synchronous motor, the flexibility of the load causes the speed oscillation. With the PI regulator as the controller, it is hard to inhibit the oscillation. What is more, the limitation of the bandwidth of the speed loop makes the phenomenon worse. The combination of the state observer and state feedback controller can eliminate the influence of the flexibility with the existing information. Then with the PI regulator, the fluctuation of the speed can be completely eliminated. The simulation results verify the effectiveness of the method.
