改进型单神经元PID控制多电机同步传动系统

通过分析传统多电机同步传动系统的不足,引入了一种改进型PID智能控制策略。用同一给定转速作为系统的主令参考信号,采用单神经元自适应PID控制算法对各台电机的转速环PID参数进行自整定,并加入前馈补偿环节,以消除负载扰动带来的转速误差。仿真结果表明,该方法不仅能使系统保持良好的跟随性能,而且大大降低了系统中某电机负载发生变化引起的同步误差现象,较传统的PI控制具有更好的动、静态特性。

Synchronous-Drive System of Multi-Motor Based on Improved Single Neuron PID Controller

Based on the analysis of traditional synchronous-drive system of multi-motor, an improved PID intelligent control strategy was proposed to control every permanent-magnet-synchronous-motor. The PID parameters of each motor system were adopted by a single neural element self-adaptive PID controller, and a feed-forward compensator was added to it to eliminate speed errors from load disturbances. Simulation results demonstrated that this control method with higher dynamic and static performance can not only keep good output-tracking but also reduce synchronous error phenomenons caused by load changes greatly.
