摘要
基于五桥臂逆变器供电的两台三相永磁同步电机系统,提出了一种基于模型预测方式的控制策略。在空间矢量脉宽调制的基础上,分析了五桥臂双电机控制数学模型;利用所建立的数学模型,本文提出的模型预测控制策略能够筛选出合适的空间电压矢量,在保证两电机速度独立控制的同时,缩短系统动态调节时间。仿真和实验结果验证了该控制策略的可行性和有效性。
A model predictive control strategy is proposed for two three-phase magnet synchronous motors with fiveleg voltage source inverter in this paper. The mathematic model of the two motors with five-leg inverter is analyzed based on space vector modulation. The suitable voltage vector could be selected by the model predictive control strategy based on the mathematic model. The dynamic response time could be shortened,and the speed of two motors could be controlled independently. The validity of this strategy is verified by the simulating experimental results.
