摘要
To address the load disturbance issues inherent in practical permanent magnet synchronous motor (PMSM) control systems, this paper proposes the integration of a super-twisting sliding mode algorithm into the load observer design. The mathematical model of the PMSM is established and discretized, and the signum function is replaced with an S-function, thereby enabling the incorporation of the estimated torque value into the q-axis current control loop. By employing load torque feedforward compensation, the proposed scheme effectively mitigates disturbances-induced fluctuations in stator current and rotor position, alleviates the chattering phenomenon prevalent in conventional sliding mode observers, and enhances the dynamic response speed of the system. Simulation and experimental results both confirm that the super-twisting sliding mode observer outperforms conventional sliding mode control methods.
