Outline
A synchronous reluctance motor (SynRM) exhibits significant magnetic saturation effect, which will lead to rotor position observation errors when using traditional high-frequency voltage injection methods. To address this issue, a rotor stationary method is employed to detect the flux linkage model of SynRM, and a nonlinear model that accounts for magnetic saturation effect is established. Based on this model, a high-frequency current response model for SynRM is constructed, and its stability is analyzed and optimized. Under heavy-load conditions, the magnetic saturation effect of SynRM intensifies. By introducing injection tilt angle signal compensation in a high-frequency injection reference frame, the instability issue of the rotor position observer is resolved, enhancing the control stability. Under light-load conditions where the saliency of the motor is weak, a q-axis minimum current limitation strategy is designed to improve the motor’s saliency. Experimental results demonstrate that the proposed control method achieves stable operation of SynRM under all the operating conditions at zero and low speeds, exhibiting anexcellent control performance.
