针对2台无刷直流电机同步连轴存在强制同速、转矩耦合以及参数漂移等问题，提出一种基于模糊控制的转矩均衡控制策略。构造速度和转矩双闭环均衡控制系统，同时满足系统的速度给定跟踪与转矩均衡控制。在速度控制环，给定转速与无刷直流电机反馈转速的转速差经过转速调节器，得到统一的转矩指令；2台电机反馈转矩与给定转矩分别进行比较，转矩差进入转矩调节器，构成2个转矩闭环，快速跟随转矩指令。在Matlab/Simulink 环境下，建立双电机同步连轴转矩均衡控制系统仿真模型，仿真对比了电机在参数一致和异常2种状况下直接转矩控制和模糊控制2种方案的结果，验证了所提控制策略的有效性。

Considering mandatory synchronization,torque coupling and parameter drifting among two brushless DC motors with synchronous shafts,a novel two??motor torque balance control scheme based on fuzzy control is presented.A double loop??closed control of speed control and torque balance is realized sim-ultaneously with meeting the speed control and power balance control system,in which torque servo master??slave control method is used.In speed control loop,the result of comparing given speed and the feedback speed of brushless DC motor gets access to the speed regulator to obtain the unified torque command.The other result of comparing the given speed and the torque feedback of brushless DC motors comes into the torque regulator to constitute two torque closed loops to rapidly follow the unified torque command.In Matlab/Simulink environment,the model of two motors torque balance control is built and a simulation of the working state of motors is conducted in normal and abnormal electrical parameters.The simulation re-sult shows that the proposed scheme is valid.
