Self-disturbance-rejection control of PMSM based on snow-ablation optimization algorithm

Abstract To address the issue of suboptimal performance of traditional PI control for Permanent Magnet Synchronous Motors (PMSM), Active Disturbance Rejection Control (ADRC) is employed for PMSM control. Additionally, due to the multitude of parameters in ADRC and the difficulty in tuning them, a Snow-Ablation Optimization (SAO) algorithm is proposed for ADRC parameter tuning. The experimental results of PMSM speed control demonstrate that compared with traditional PI control and Particle Swarm Optimization (PSO) based ADRC, the SAO-tuned ADRC method proposed in this paper has no overshoot and exhibits good control performance.
