MATLAB下汽車運(yùn)動(dòng)控制簡(jiǎn)化模型的PID校正

本文并初步探討了汽車運(yùn)動(dòng)的控制算法,包括橫向控制算法和縱向控制算法, 并建立起汽車運(yùn)動(dòng)控制系統(tǒng)的簡(jiǎn)化模型。在MATLAB 環(huán)境下對(duì)汽車運(yùn)動(dòng)控制系統(tǒng)進(jìn)行PID 和根軌跡的設(shè)計(jì)和校正。由此，確定汽車運(yùn)動(dòng)控制系統(tǒng)的期望靜態(tài)指標(biāo)（穩(wěn)態(tài)誤差）和動(dòng)態(tài)指標(biāo)（超調(diào)量和上升時(shí)間）。該方法簡(jiǎn)便快捷，結(jié)果準(zhǔn)確可靠，它是汽車運(yùn)動(dòng)控制系統(tǒng)設(shè)計(jì)的優(yōu)秀手段之一。

Abstract: The paper describes a control algorithm of Automobile Motion, including horizontal control algorithm and longitudinal control algorithm and then set up the simple model of auto kinetic control system. Auto kinetic control system was adjusted by PID and roots locus methods in the condition of MATLAB. There out, the static index (steady- state error) and the dynamic index (overshoot and rise time) of auto kinetic control system can be fix on. The method is simpler and more convenient, and the result is more precise and reliable, the method is excellent in the design of auto kinetic control system.
