Oscillation suppression of permanent magnet synchronous motor based on RTDS hardware-in-the-loop

Résumé fourni par la source

In actual operation, the phenomenon of oscillation in permanent magnet synchronous motors is quite common, and the occurrence of oscillation accidents may have a serious impact on the stability and reliability of the system. This article proposes a fractional-order PIλ control suppression strategy. On the basis of the eigenvalue analysis method to analyse the oscillation mechanism of the permanent magnet synchronous motor, the intrinsic oscillation frequency of the motor is calculated, and a perturbation source with the same frequency as the intrinsic oscillation frequency is introduced to excite the resonance. On the basis of traditional PI control, a fractional-order PIλ control strategy is introduced. Through tuning, the integral order of fractional-order PIλ that achieves the optimal suppression effect is obtained. The control performance of fractional-order PIλ is compared with that of traditional PI control to highlight the advantages of the fractional-order PIλ control strategy. The rationality and effectiveness of the fractional-order PIλ control strategy are verified through the RTDS hardware-in-the-loop experimental platform.
