摘　　要：针对双无刷直流电机同步控制系统运行中由于负载扰动造成同步性能差的问题,建立了无刷直流电机和同步控制系统的数学模型,在比较各种同步控制控制方式和控制算法的基础上,提出了在偏差耦合控制方式下采用变论域自适应模糊PID控制算法对偏差进行补偿调节的双无刷直流电机改进控制方案,并与采用常规PID和模糊PID算法的方案进行了比较。通过仿真结果和结论分析,表明采用变论域自适应模糊PID控制算法的偏差耦合控制系统可提高同步精度,优于采用常规PID和模糊PID算法的系统。For the operation problems of dual synchronous brushless DC motor control system due to load disturbance caused by poor synchronization performance, a mathematical model of brushless DC motors and synchronous control system is established. On the basis of comparison of various synchronization control methods and algorithm, the reforming control scheme of dual synchronous brushless DC motor is put forward by using VUFPID control algorithm to compensate and a djust the deviation under eviation coupling control. The simulation results and conclusions show that the deviation coupling control system using VUFPID control algorithm can improve the synchronization accuracy, and it is superior to conventional PID and f uzzy PID algorithm system.
