摘要
针对线控液压制动系统响应速度慢、制动轮缸控制稳定性差等问题,并结合本研究系统所具有的非线性特点,设计了适用于线控液压制动系统的模糊控制器。通过结合汽车的实际情况,在Simulink和AMESim软件中搭建了模糊控制器与线控液压制动系统的仿真模型,通过仿真对比相同输入信号下的两种控制算法对该系统响应特性影响。在仿真中,仿真的输入信号为阶跃信号和方波信号,通过分析得出制动轮缸的压力曲线。结果表明:在同一信号下,模糊控制相较于无控制(即无任何控制算法进行控制本研究系统),响应速度提升了0.15 s左右,该控制使系统具有良好的动态特性,满足系统要求。
In view of the line control hydraulic braking system response speed slow and poor stability of wheel cylinder control problem and the nonlinear characteristics of this research system. In this study,a fuzzy control algorithm is designed. By combining the actual situation of the vehicle,it established the fuzzy controller and hydraulic braking system model in the AMESim and Simulink. In the simulation,the simulation of the input signal is step signal and square wave signals,through the analysis and obtained the pressure curve of wheel cylinder. The results show that under the same input signal,compared with no control（without any control algorithm to control the system）,fuzzy control response speed up around 0.15 s,and it has the features of well dynamic characteristics,it also meets the system requirements.
