Abstract The flexible load is widely presents in the electrical drive system. According to the origin, the flexible load can be classified as the system of rigid load driven by a servo motor via a flexible coupling and flexible load driven directly by a servo motor. As for the typical system above, firstly they are modeled according to Lagrange Principle and an equivalent model is acquired. Then PI controller is used for the system control. Since there are only two degrees for PI controller, the performance is unsatisfactory. As a result, the state feedback has to be introduced. On this occasion, the load position is measured and feedback to the control system. Then the strategy is analyzed and the parameters are tuned with pole placement method. The simulation and experimental results verified the effectiveness of the load position feedback strategy and its' parameter tuning method for the system of flexible load driven by PMSM.

Key words： Permanent magnet synchronous motor(PMSM) flexible load load position feedback pole placement
