多电机同步控制建模与仿真

采用偏差耦合控制结构控制4台永磁同步电机同步运动时,由于控制器结构复杂,计算量大,而且传统的PID控制算法不能在线实时调整参数,动态响应慢。因此,对4电机同步运动控制结构和控制算法进行改进,采用环形耦合控制结构和免疫单神经元PID控制器控制整个同步运动系统。仿真结果表明:该控制结构复杂度低,跟踪性能和稳态性能良好,抗干扰性强。

Modeling and Simulation of Multi Motor Synchronous Control

When the deviation coupling control structure is used to control the synchonous movement of four permanentmagnet synchronous motors , the structure of the controller is complex and the amount of calculation is large.Moreover, thetradlitional PIlD control algorithm cannot adjust the parameters online and in real time, and the dynamic response is slow.Therefore, the four motor synchronous motion control structure and control algorithm are improved, and the ring couplingcontrol structure and immune single neuron PID contmoller are used to control the whole synchronous motion system.Thesimulation results show that the control structure has moderate complexity , good tracking peformance and stabilizing per-formance , and strong anti-interference.
