N2 - To address the low-speed instability issues in permanent magnet synchronous motor (PMSM) control systems employing sliding mode control (SMC), this study proposes an enhanced SMC algorithm incorporating a novel reaching law. The developed methodology not only significantly suppresses buffeting and shortens system response time, but also improves dynamic stability of PMSM operation. Additionally, a disturbance observer is integrated to estimate lumped disturbances for enhancing the system's disturbance rejection capability. Comparative simulations demonstrate that the proposed improved SMC reduces oscillation amplitude by 97.5% and 66.7% respectively when benchmarked against traditional PI control and arctangent-based SMC systems. Correspondingly, recovery time shows 75% and 16.7% reductions compared with these two conventional approaches. These quantitative results confirm the proposed control system achieves superior transient performance with accelerated response characteristics and minimized buffeting effects.
