High performance permanent servo drive system requires fast current loop response to improve whole system dynamic performance. In digital PMSM control system, time delay is inevitable since PWM updates at a regular frequency. Traditional PID algorithm which is widely used in industrial application may cause overshoot when improve current response. And conventional current predictive control method depends on accurate object model parameters. In this paper, a new current control based on the adaptive disturbance rejection control(ADRC) is proposed to improve the current response by compensate time delay and implement high-performance motion control of permanent magnet synchronous motors. Matlab simulation and experimental results verify the new current controller based on ADRC algorithm achieves better current response. Also, it has strong robustness for parameters variation and disturbance.
