AI Technical Summary
Traditional sliding mode control methods are difficult to simultaneously meet the requirements of chatter suppression and convergence speed under parameter perturbation and external disturbance in permanent magnet synchronous motors, and stator current waveform distortion and torque pulsation affect the system control accuracy and stability.
An adaptive non-singular terminal sliding mode control (ANTSMC) method based on parameter identification is adopted. By establishing a current loop model in the dq axis coordinate system and combining it with an Adaline neural network to identify motor parameters, an ANTSMC is constructed to achieve online compensation and robust control of motor parameters.
It effectively suppresses chattering, reduces overshoot, improves the robustness of the controller to parameter perturbations and external disturbances, enhances control accuracy and stability, and ensures efficient operation of the motor.
