摘　　要：针对多电机协同控制,设计了一种参数自整定模糊PID多电机同步控制策略,将模糊控制和传统PID控制相结合原理,利用模糊推理判断的思想,根据多电机速度偏差、偏差变化率的不同对PID控制器的参数进行在线整定,从而做到PID控制器的参数随多电机速度偏差和偏差变化率实时变化。仿真结果表明,该自整定模糊PID控制算法收敛速度快、稳定性能好,能很好的实现多电机比例协同控制,具有较高的同步精度和动态性能。For multi-motor coordination control, we design a deviation rate of change of the parameters of fuzzy self-tuning PID multi-motor synchronous control strategy, the fuzzy control and PID control combines the traditional theory, the use of fuzzy inference judgment ideological deviation based on multi-motor speed, the different parameters of PID controller tuning online, so do the parameters of a PID controller with multi-motor speed deviation and the deviation rate of change in real-time change. Simulation results show that the fuzzy self-tuning PID control algorithm convergence speed, good stability, can achieve a good proportion of collaborative multi-motor control, with high synchronization accuracy and dynamic performance.
