Abstract

Traditional sensorless control methods suffer from performance degradation at low speeds and under parameter variations. The introduction of sliding mode control effectively addresses this issue. In this paper, a mathematical model of the PMSM is first established, and an improved sliding mode observer is designed. Through robust analysis of key motor parameters such as stator resistance, inductance changes, and flux linkage deviation, it is found that sliding mode control exhibits strong disturbance rejection capability against resistance changes, moderate robustness against inductance changes, while flux linkage deviation significantly affects system accuracy. Experimental results demonstrate that the sliding mode control scheme exhibits significant advantages over traditional methods in terms of low-speed observation accuracy, dynamic response speed, and system overshoot control. The feasibility of this control method in industrial applications is validated through experiments, particularly under high-load conditions, where it demonstrates good robustness.
