Abstract: Aiming at the problem of voltage limit ellipse constraint and current parameter tuning in high-speed flux weakening region of interior permanent magnet synchronous motor, a hybrid flux weakening control strategy based on finite set predictive current control method and real-time voltage feedback is proposed. Firstly, the finite-set predictive current control method is used to calibrate the torque, speed, current and angle in the maximum torque current ratio and flux weakening region, which solves the traditional complex current parameter setting problem and improves the reliability of calibration data. Secondly, on the basis of predictive current sampling control method, combined with real-time voltage feedback, a hybrid flux weakening control strategy is designed to avoid the parameter setting of current loop, solve the problem of voltage limit ellipse constraint and realize high-speed operation. Finally, the effectiveness of the proposed method is verified by simulation and experiment.
