ACTIVE DISTURBANCE REJECTION CONTROL STRATEGY OF PMSM BASED ON IMPROVED DPCC
When the vector control system of traditional permanent magnet synchronous motor(PMSM)was disturbed by the outside interference,it is easy to cause violent fluctuation in speed and electricity.To solve the above problems,an active disturbance rejection control(ADRC)strategy for PMSM based on improved deadbeat predictive current control(DPCC)was proposed.Firstly,the ADRC controller was designed for the speed loop,which replaces the traditional PI controller,and the ADRC would self-adjust according to the strength of the disturbance.Secondly,the improved DPCC was used in the current loop to improve the control accuracy of the whole system.Finally,the speed loop ADRC+ current loop improved DPCC was compared with the traditional PMSM vector control system and the speed loop PI + current loop improved DPCC by simulation in Matlab/simulink.The results show that compared with the traditional PMSM vector control system and the speed loop PI+ current loop improved DPCC control system,the speed loop ADRC+ current loop improved DPCC control system has smaller overshoot and stronger anti-interference ability.
