| 中文摘要: |
| 针对传统PI算法难以消除直流无刷电机控制系统中存在的系统超调和短时震荡的问题，提出将模糊控制技术融入到PI控制器参数整定过程，设计模糊PI自适应控制器，并搭建电机模糊控制系统的仿真模型。仿真实验结果表明，基于模糊PI控制的电机控制系统相比传统PI控制系统达到给定转速所需时间更短，抗干扰性更强，ITAE（时间乘绝对误差积分准则）值更低，表明在负载突变时模糊PI控制器能更有效抑制电机转矩脉动和提高控制系统的稳定性。 |

| Aiming at the traditional PI algorithm difficult to eliminate BLDCM control system overshoot and oscillation, the fuzzy control technology was proposed to be integrated into the parameter tuning process of PI controller. The fuzzy PI controller was designed and simulation model of motor was structured based on fuzzy PI algorithm. The result shows that the motor control system based on fuzzy PI uses less time from initial state to theoretic speed, and the rotation speed can maintain constant under disturbance. The ITAE is fewer than the PI control system which shows that the fuzzy PI controller can effectively restrain the motor torque ripple and improve the stability of the control system under abrupt load variation. |
