摘要

Permanent magnet synchronous motors are highly coupled, multivariable, and nonlinear, and sliding mode control has gradually gained traction in motor control systems due to its robustness. However, conventional sliding mode control suffers from issues such as severe chattering and insufficient convergence speed. To address these limitations, we propose an integral sliding mode control strategy, enhanced by an improved power exponential reaching law (IPERL). This strategy integrates an IPERL based on state error and an integral sliding mode surface, enabling the system to respond rapidly to changes in operating conditions while effectively mitigating oscillatory behavior. The proposed control strategy is validated through simulations, demonstrating its superior performance compared to traditional methods in terms of both stability and convergence speed.
