摘要
以多变量非线性强耦合的双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,建立双台电机系统的数学模型。采用单神经元自适应PSD控制器,对多电机同步系统的速度和张力进行解耦控制。实验结果证明了该控制系统在动态性能、稳态性能、跟踪性能方面均优于传统的PID控制器,可以实现系统转子转速和皮带张力的解耦,满足实际生产的要求。
The paper takes the multi-variable of synchronization system of the AC induction motors as study object, focuses on the system of induction motors powered by current-tract SPWM transducers, the unified mathematical model of the system of two motors depends on α, β static reference is established. It adopts a single neuron adaptive PSD controller to perform the decoupling control of speed and tension of the system. The rsuhs of experiment prove that the control system has higher dynamic and status and follwing performances than traditional PID, and realize the decoupling control of speed and tension of the system. The control system has good application prospects.
