摘要
为了实现智能汽车精确、快速、稳定的制动力控制,设计了一种电子液压制动系统,通过对该系统进行建模分析,结合电机控制,基于自抗扰控制方法,设计了 一种主缸液压力串级控制器,利用AMEsim软件进行建模标定,并进行仿真分析,仿真结果表明,所提出的自抗扰控制器在系统最大建压150 bar的情况下,超调量为1.3％,控制精度优于PID控制器(超调量10％),不同目标主缸压力下的控制效果也优于PID控制器.
Abstract
To achieve precise,fast,and stable braking force control for intelligent vehicles,an electronic hydraulic bra-king system was designed.By modeling and analyzing the system,combined with motor control,and based on the self dis-turbance rejection control method,a master cylinder hydraulic pressure cascade controller was designed.AMEsim software was used for modeling and calibration,and simulation analysis was conducted.The simulation results showed that,The proposed self disturbance rejection controller has an overshoot of 1.3％under a maximum system pressure of 150 bar,with better control accuracy than the PID controller(overshoot of 10％).The control effect under different target master cylinder pressures is also better than the PID controller.
