| Abstract: | In order to improve reliability of electric excitation synchronous motor control system and optimize its performance speed,a model predictive current control strategy for electric excitation synchronous motor speed sensorless . The model predictive current control is used as the current loop instead of the traditional PI regulator, which effectively suppresses the current ripple and improves the current tracking performance. Based on the model reference adaptive theory an electric excitation synchronous motor speed sensorless is designed to identify the running speed of the motor online,and realize accurate estimation of speed. The simulation results show that the control system is fast and reliable. |
