| Abstract: | The reversiblily of the asynchronous motor system on the condition of dynamic decompositon is proved, and the approximate inverse system is derived according to nonlinear system theory. Then, with the inverse system as the feedforward controller to supply basic control signal, PID controller as the feedback controller producing compensate signer to overcome the errors of the approximate inverse system and the disturbances, a asynchronous motor compound control system is contructed. The simulation results demonstrate that the speed tracking performance and robust performance of the proposed system are excellent. |
