AESO-based dead-beat current prediction fuzzy control method for permanent magnet synchronous motor

According to the AESO-based dead-beat current prediction fuzzy control method for the permanent magnet synchronous motor, a fuzzy controller is combined in a traditional method based on an extended state observer, gain parameters are switched according to different current working conditions, the response speed of the current is increased, overshoot and oscillation during current step are reduced, and the stability of the current step is improved. And the current following stability is ensured. According to the method, the disturbance caused by parameter mismatch is observed, feedforward value compensation is performed on the control voltage, and the sampling current in the control voltage equation is replaced by the predicted current, so that the disturbance caused by one-step delay error and parameter mismatch is improved, and the robustness of motor control under complex parameter mismatch of various working conditions is improved. According to the method, the problem of sensitivity of traditional current
