摘要
为了改善车辆新型制动系统的性能,提高其响应特性,在分析其工作原理的基础上,建立了本研究系统的整体数学模型,设计了与本研究系统相符合的模糊控制器和PID控制器。通过结合车辆的实际情况,在Simulink和AMESim中搭建了与实际线控液压制动系统相吻合的仿真模型,通过仿真对比相同输入信号下的两种控制算法对本研究系统响应特性的影响。结果表明:模糊控制相较于PID控制,响应速度提升了0.1s左右,相较于无控制策略,响应速度提升了0.15s左右。
In order to improve the performance of the new vehicle braking system and improve the response characteristics,the subject based on the analysis of its working principle has established a mathematical model of the overall system of the present study,and designed a fuzzy controller and PID controller.By combining the actual situation of the vehicle,built in Simulink and AMESim simulation model coincide with the actual wire hydraulic brake system through simulation comparing the two signals at the same input control algorithms on the response Characteristics of the research system. The results showed that： Compared to PID control,fuzzy control is faster response about 0.1 s,compared to non-control strategy,enhance the response speed of about 0.15 s.
