摘要
本文首先在MATLAB2023b/Simulink环境中搭建出基于滑移率控制的ABS动力学模型,采用模糊PID控制与经典的PID控制对车辆制动过程仿真,通过对比两者在干燥路面、潮湿路面上车速与轮速曲线、滑移率曲线、制动减速度曲线以及制动距离曲线,分析模糊PID控制对车辆制动效果的提升。通过试验得出:模糊PID控制在干燥路面的制动距离减少0.642m,潮湿路面减少1.55m。模糊PID控制在扰动的干燥路面制动距离减少1.562m,在扰动的潮湿路面制动距离减少1.6m,进一步证明了模糊PID控制的有效性。
In this paper,the ABS dynamics model based on slip rate control was fi rst built in MATLAB2023b/Simulink environment,and the vehicle braking process was simulated by fuzzy PID control and classical PID control.By comparing the vehicle speed and wheel speed curve,slip rate curve,braking deceleration curve and braking distance curve on dry road and wet road,the improvement of vehicle braking eff ect by fuzzy PID control is analyzed.The experiment results show that the braking distance of fuzzy PID control on dry road is reduced by 0.642m,and that on wet road is reduced by 1.55m.The braking distance of the fuzzy PID control on the disturbed dry road is reduced by 1.562m,and that on the disturbed wet road is reduced by 1.6m,which further proves the eff ectiveness of the fuzzy PID control.
