| 针对目前国内汽车轮毂轴承试验机存在测试系统不稳定、精度差、速度响应慢等缺陷，提出将汽车轮毂轴承试验机测控系统由传统的PID控制改为FPID控制的方法，并根据专家经验和技术要求，确定FPID控制的两输入三输出；然后通过MATLAB建立49条模糊规则，在生成模糊控制视图后，利用Simulink搭建仿真模型。结果显示，该FPID控制的测控系统动态响应速度快，较传统PID控制提高2 s；达到稳定状态时间较传统PID控制缩短10 s，且FPID控制趋于稳定后不存在大的波动。 |

| Aiming at the shortcomings of the current automotive wheel bearing test machine, such as unstable test system, poor precision and slow speed response, this paper proposes to change the measurement and control system of the automobile wheel bearing test machine from the traditional PID control to the FPID control method. According to expert experience and technical requirements, two inputs and three outputs of FPID control are determined. Then 49 fuzzy rules are established by MATLAB. After generating the view of fuzzy control, the simulation model is built by Simulink. The results show that the FPID controlled measurement and control system has a fast dynamic response speed, which is 2 s higher than the traditional PID control. The steady state time is shortened by 10 s compared with the conventional PID control, and there is no large fluctuation after the FPID control tends to be stable. |
