Abstract
En 中文
To solve the coordinated optimization of dynamic response, steady-state accuracy and chattering suppression in PMSM speed control, an INISMC-ADSTA strategy is proposed. Its nonlinear piecewise sliding mode surface alleviates the conflict between integral saturation and dynamic performance, while the adaptive super-twisting reaching law achieves fast convergence and chattering suppression. Verified by Lyapunov stability analysis, finite-time convergence proof and DSP experiments, the strategy optimizes multiple performance indicators coordinately with strong disturbance rejection, outperforming traditional methods.
