摘　　要：以现有的汽车行驶速度随动系统数学模型为基础,将模糊PID控制算法引入其中,使系统的快速性、稳定性较常规PID控制算法有进一步的提高,并在simulink仿真软件中,组建汽车行驶速度随动系统的仿真模型,将模糊PID控制算法与常规PID控制算法的仿真结果进行比较,结果表明,使用模糊PID控制算法后,汽车行驶速度随动系统的超调量可减少12.6%,系统调整时间可减少6 s。该研究对提高汽车行驶速度随动系统的性能有一定参考价值。Based on the mathematics model of automobile speed servo system, using the fuzzy PID control algorithm, the response speed and stability of the system had an improvement compared with conventional PID control algorithm. To compare fuzzy PID control algorithm with traditional one, the simulation model of automobile speed servo system had been built in simulation software. The simulation results show the overshoot of system can reduce 12.6% and the adjust time can decrease 6 s after using fuzzy PID control algorithm. The research had a certain value to the performance of the car speed servo system.
