| Abstract: | In order to achieve precise and steady control of axial hybrid magnetic bearings(HMB) of bearingless motors,an active disturbance rejection control(ADRC) system based on the theory of ADRC for the axial HMB is designed.The control arithmetic and configuration are given.According to parameters of the experiment rig,the simulation system was set up with Matlab software.The step response of system,the start up displacement curve of rotor and the performance of anti-disturbance of system were simulated and analyzed.The simulation results show that the active disturbance rejection control system is effective to the high-quality needs of the axial HMB with high precision,high speed of response and strong anti-disturbance. |
