Abstract EN
Existing research studies on torque ripple suppression mostly ignore the electrical loss of PMSM.
However, the electrical loss will not only decrease the operating efficiency but also adversely influence the suppression of torque ripple.
This paper attempts to construct a unified framework to suppress torque ripple with consideration of electrical loss.
Firstly, a dynamic mathematical model of PMSM under current vector orientation is established with a combination of electrical loss.
The constraints that can achieve the control of both torque ripple and electrical loss for PMSM are derived.
Then, on the basis of the backstepping control principle, a closed-loop I/f integrative control method under stator current vector orientation is proposed.
Meanwhile, this paper also proposes a speed estimation algorithm of PMSM based on the least-squares method to realize wide-range speed identification and an online prediction algorithm for control parameters of backstepping control to enhance the stability of the motor in operation.
Both simulations and experiments have been performed to verify the effectiveness of the proposed control method, and the results indicate that torque ripple is suppressed effectively, operating efficiency is significantly improved, and all variables are regulated to track their reference signals correctly and rapidly.
