Abstract:A modified model compensation active disturbance rejection controller (MMC-ADRC) is proposed, which has better tracking performance for speed-regulation system of permanent magnetic synchronous motor (PMSM) with time-varying input. Model compensation is used to decrease the observed disturbance of extended state observer (ESO) so as to improve the observation accuracy. When the input is time varying, the tracking performance of the system is poor according to the modelling errors in conventional ADRC. The tracking errors can be reduced by enlarging controller gain, but the control performance is deteriorated because of amplified noises. Adding input derivative feed forward (IDF) will realize better tracking performance, which can eliminate the modelling errors theoretically. Extensive comparative simulation and experiment tests are performed. The results show the improved performance of the proposed algorithm. © 2017, The editorial office of Transaction of China Electrotechnical Society. All right reserved.
