摘要 传统PI调节器是在同步坐标系下对定子电流的磁化分量im和转矩分量it进行控制。但在多输入、多输出,特别是变量间存在耦合时调节效果并不理想,加入前馈解耦环节后能改善性能,但动态解耦效果并不明显。针对传统PI调节器、前馈补偿PI调节器在电励磁同步电动机电流内环调节中存在的不足,对电流内环进行复矢量建模与分析,结合零极点图分析,研究了一种新颖的电流调节器。仿真结果表明,该电流调节器能明显改善电励磁同步电动机MT轴电流间的动态耦合,具有一定的抗干扰性和鲁棒性。 传统PI调节器是在同步坐标系下对定子电流的磁化分量im和转矩分量it进行控制。但在多输入、多输出,特别是变量间存在耦合时调节效果并不理想,加入前馈解耦环节后能改善性能,但动态解耦效果并不明显。针对传统PI调节器、前馈补偿PI调节器在电励磁同步电动机电流内环调节中存在的不足,对电流内环进行复矢量建模与分析,结合零极点图分析,研究了一种新颖的电流调节器。仿真结果表明,该电流调节器能明显改善电励磁同步电动机MT轴电流间的动态耦合,具有一定的抗干扰性和鲁棒性。
