| 摘 要： | 基于船用三相交流电机直接转矩增加模糊PI控制,改善电机的调速性能。根据三相交流电机数学模型,和按定子磁链控制的直接转矩控制理论,再增加模糊PI进行偏差调节,最后用Matlab/Simulink软件搭建电机仿真模型。实验结果表明基于模糊PI的三相交流直接转矩电机系统比传统PI控制的电机响应速度更快、动稳态性能更好,可满足实际电机调速要求。

| Abstract: | Based on the direct torque of the three-phase AC motor of marine,the fuzzy PI control is added to improve the speed regulation performance of the motor. According to the mathematical model of three-phase AC motor,and the direct torque control theory based on stator flux linkage control,the fuzzy PI is added to adjust the deviation.Finally,the motor simulation model is built by Matlab/Simulink software. The experimental results show that the threephase AC direct torque motor system based on fuzzy PI has faster response speed and better dynamic steady state performance than the traditional PI control motor,which can meet the actual motor speed regulation requirements. |
