Multi-Voltage Vector of Duty Cycle Model Predictive Current Control for Permanent Magnet Synchronous Motor

摘要

In order to improve the dynamic performance of motor control, the duty cycle control in current control and multi-voltage vector control are combined to propose a multi-voltage vector duty cycle model predictive current control method. In this paper, the optimal vector control combined with zero vector is used. The stator current is predicted by using the current state equation and Euler method. The duty cycle of the optimal vector control is calculated by combining the value function. The speed response, current and torque ripple of different control modes are compared. The simulation results show that the method improves the dynamic response speed and reduces the torque and current ripple.
