Abstract

A first-order Active Disturbance Rejection Controller(ADRC) with an arc-hyperbolic sine function was presented to increase the tracking precision of the Sinusoidal Pulse Width Modulation(SPWM) speed governing system of a Permanent Magnet Synchronous Motor(PMSM). A mathematical model for the velocity loop of the PMSM was studied. Then a first-order tracking differentiator and a second-order extended state observer were designed respectively and their convergences were analyzed by using the Lyapunov function. The first-order ADRC of the velocity loop was constructed

and the asymptotic stability of the first-order ADRC error system was verified. Finally

the designed first-order ADRC was used as the rotating speed adjuster of the SPWM

and the SPWM speed governing system with the ADRC was analyzed. Simulation experiments demonstrate that the speed step response adjustment time of the SPWM speed governing system with the ADRC is 0.15s

the steady error is less than 0.28 r/min

and the maximum sine tracking error is 17 r/min. As compared with a PI controller

the governing system with the ADRC is characterized by fast and stable step response

smaller stable error and no overshoot. Moreover

it shows better sine tracking performance and smaller tracking errors.
