英文摘要 |
To improve the stability and disturbance rejection for the suspension system for a bearingless motor of permanent magnet type, a mixed sensitivity robust control strategy is proposed based on the operating principle of suspension system. The controller is designed by selecting the appropriate sensitivity and complementary sensitivity weighting functions. The suspension control system for the bearingless motor with rotor flux orientation is also implemented on the basis of proposed controller. Simulation results show that the performances of the proposed controller are superior to those of the traditional PID controller with the robustness in modeling the system and disturbances. The validity of proposed algorithm is also effectively evaluated by experiment study. |
