Control Structure
控制器設計的主要目的是保持
以下車輛的期望車輛間距,以及
最小化穩态距離誤差。當上司
車輛以恒定速度行駛時,車輛的誤差
間距不應過大。當領先的車輛
加速或減速時,間距誤差将增大或減小
由于下列車輛的反應時間減少
排。在這種情況下,控制器應能夠確定
確定車輛不會碰撞
當選擇不同的期望車輛間距作為
控制目标,控制器能使卡車形成穩定的工作狀态
排在本文中,控制器采用分層控制。
上層控制器基于模糊控制。輸入是
車輛的速度誤差和跟車距離誤差
受控車輛,輸出為所需加速度。
下部控制器用于調節節氣門開度和開度
車輛的制動力。輸入為上層控制器計算的期望加速度,輸出為
節氣門開度或制動分泵壓力。調整
節氣門開度和輪缸壓力基于
關于PID算法。給出了控制器的結構
如圖4所示。

The Lower Controller
下部控制器用于調節節氣門開度和開度
車輛的制動力。輸入為上層控制器計算的期望加速度,輸出為
節氣門開度T或制動分泵壓力P
下部控制器需要計算所需的節氣門開度
ith的Tdes和所需制動缸壓力Pdes
車輛,根據ades,i
. 調節節氣門開度和節氣門開度
輪缸壓力基于PID算法。
當控制第i輛車的加速度時
節氣門開度T等于所需的節氣門開度Tdes
加上PID控制器的輸出。此時
PID控制器是ades和i之間的差別
和a。如圖所示
