本文提出一种永磁同步电机实时自适应电流控制方案，在预测电流控制的基础上增加参数辨识，用来克服电机参数不准确带来的影响，用比较计算模型和实际电机输出之间的差别的方法对电枢电感和永磁磁通参数进行辨识。给出了基于DSP的系统的实现方法及仿真与实验结果。 In this paper, a real-time adaptive current control scheme of permanent magnet synchronous motor is proposed. Based on the predictive current control, parameter identification is added to overcome the inaccuracy of the motor parameters. The difference between the calculated model and the actual motor output is compared Method to identify armature inductance and permanent magnet flux parameters. The implementation method of DSP-based system and its simulation and experimental results are given.
