基于固定开关频率的永磁同步电机预测电流控制
Predictive Current Control of Permanent Magnet Synchronous Motor Combined with Fixed Switching Frequency
摘要
Abstract
To achieve high performance permanent magnet synchronous motor control ,a new predictive current control of permanent magnet synchronous motor combined with magnetic field orientation was proposed. At first ,cost function and the corresponding constraints of the controller were designed based on d-q axis current through the field oriented principle,and then the discrete motor mathematical model and the iterative algorithm were used for solving the optimal voltage vector,and the final calculation results were sent to space vector pulse wide modulation to realize the motor driven at fixed switching frequency. The comparative test results between the traditional control strategy and the new method show that the dynamic performance of the new control scheme is significantly better than that of the traditional control strategy.关键词
