摘　　要：针对双电机同步驱动控制在负载发生扰动时同步控制性能较差的问题,建立了双无刷直流电机偏差耦合同步控制系统的数学模型,提出了智能PI控制器作为速度补偿器的同步控制方案.智能PI控制器可有效缓解普通PI控制系统快速性和平稳性的矛盾,使系统具有更高的同步控制精度.仿真结果表明,采用智能PI控制的系统优于采用普通PI控制的系统.For the problem of synchronous performance of double - motor being at a low - level with disturbance of the drive motors＇ load, the math model of double - motor＇ s sync - drive control system for brushless DC motor is built, and based on the relative coupling strategy and the intelligent PI as speed compensator to control the double -motor＇s relative is presented. Compared with common PI control system, the intelligent PI control system suc- cessfully solves the contradiction between quickness and smoothness. Simulation results show that the system of rel- ative coupling which adopt intelligent PI is better than common PI＇ s.
