摘要
以多变量非线性强耦合的多电机同步控制系统为研究对象,针对电流跟踪型SPWM变频器供电的感应电机系统,在α,β静止坐标系下,建立两台电机系统的统一数学模型。采用多变量单神经元自适应PSD控制器,实现了多电机的转子转速和皮带张力的解耦控制。仿真和实验结果证明了该控制器具有较高的快速性和控制精度且具有较强的鲁棒性。
Takeing of multi-motor synchronization system of the multi-variable as study object, focuselng on the system of induction motors powered by current-tract SPWM transducers, the unified model of the system of two motors depends on the α,βstatic reference frame is established. It adopts the adaptive PSD controller with multi-variable single neural unit,and realizes the decoupling control of speed and tension. The results of simulation and experiment prove that the controller has higher speediness , fine control precision and good robust.
