摘　　要：双电机同轴硬联运行时,2台电机速度被强制同步,由于2台相同电机参数略有差异,导致功率分配不平衡,针对这一问题提出了基于直接转矩控制的双电机主从模糊控制系统。基于功率平衡要求,通过MATLAB仿真分析双电机运行负载分配情况,提出双电机功率平衡运行条件。根据直接转矩控制,使用主从控制和传统PID设计的系统基本上解决了功率不平衡问题,但其动态性能不佳。为了改善动态性能,设计了"模糊参数自整定PID"控制器。仿真结果表明,该系统最终达到了功率平衡,有效防止双电机同轴运行时1台电机负载过大的问题,而模糊参数自整定PID与传统PID控制的系统相比,可以提高功率跟踪的动态性能。Two motor＇s speed is forced synchronization during the coaxial dual-motor running.Due to the slight difference in the two identical motor parameters,it will lead to uneven distribution of power and a fuzzy control system of two motor master-slave based on direct torque control is put forward.Based on the power balance requirements and load condition of dual-motor by MATLAB simulation analysis,the power balance condition of dual-motor was proposed.Based on direct torque control,the use of master-slave control and conventional PID system was basically designed to solve the problem of power imbalance.But its dynamic performance was poor.The ＂fuzzy parameter self-tuning PID＂ was designed to improve the dynamic performance.Simulation results show that the fuzzy parameters from the system compared with conventional PID tuning PID control can improve the dynamic performance of the power track.
