摘要
为解决多电机同步控制难以满足高精度控制和比例同步控制的问题,提出一种改进型偏差耦合控制结构系统。根据每台电机的运行状态进行速度补偿,采用模糊PID控制器替换固定增益,结合速度补偿模块结构原理,对速度控制器进行改进,建立永磁同步电动机的控制仿真模型,并对3台电机改进偏差耦合控制进行仿真分析。仿真结果表明:与传统的固定增益控制策略相比,该改进型控制系统的自适应模糊PID控制策略具有更高的同步稳定性。
In order to solve the problem that multi-motor synchronization control can not meet high precision control and proportional synchronization control, an improved deviation coupling control structure system is proposed. According to the running state of each motor, speed compensation is carried out, and fixed gain is replaced by fuzzy PID controller. Combining with the structure principle of speed compensation module, the speed controller is improved. The control simulation model of permanent magnet synchronous motor is established, and the improved deviation coupling control of three motors is simulated and analyzed. The simulation results show that compared with the traditional fixed gain control strategy, the adaptive fuzzy PID control strategy of the improved control system has higher synchronization stability.
