Control Structure
控制器设计的主要目的是保持
以下车辆的期望车辆间距,以及
最小化稳态距离误差。当领导
车辆以恒定速度行驶时,车辆的误差
间距不应过大。当领先的车辆
加速或减速时,间距误差将增大或减小
由于下列车辆的反应时间减少
排。在这种情况下,控制器应能够确保
确保车辆不会碰撞
当选择不同的期望车辆间距作为
控制目标,控制器能使卡车形成稳定的工作状态
排在本文中,控制器采用分层控制。
上层控制器基于模糊控制。输入是
车辆的速度误差和跟车距离误差
受控车辆,输出为所需加速度。
下部控制器用于调节节气门开度和开度
车辆的制动力。输入为上层控制器计算的期望加速度,输出为
节气门开度或制动分泵压力。调整
节气门开度和轮缸压力基于
关于PID算法。给出了控制器的结构
如图4所示。

The Lower Controller
下部控制器用于调节节气门开度和开度
车辆的制动力。输入为上层控制器计算的期望加速度,输出为
节气门开度T或制动分泵压力P
下部控制器需要计算所需的节气门开度
ith的Tdes和所需制动缸压力Pdes
车辆,根据ades,i
. 调节节气门开度和节气门开度
轮缸压力基于PID算法。
当控制第i辆车的加速度时
节气门开度T等于所需的节气门开度Tdes
加上PID控制器的输出。此时
PID控制器是ades和i之间的区别
和a。如图所示
