車輛主動(dòng)懸架LQG控制器的設(shè)計(jì)與仿真分析-車輛主動(dòng)懸架LQG 控制器的設(shè)計(jì)與仿真分析.rar
　通過建立1/2 車輛模型和路面輸入模型, 應(yīng)用最優(yōu)控制理論進(jìn)行了車輛主動(dòng)懸架的LQG 控制器的設(shè)計(jì), 并在Matlab/Simulink 環(huán)境中建立系統(tǒng)模型并進(jìn)行仿真模擬, 將主、被動(dòng)懸架的車身加速度、仰俯角加速度、懸架動(dòng)撓度及車輪動(dòng)位移4 項(xiàng)指標(biāo)進(jìn)行了對(duì)比分析。仿真結(jié)果表明, 具有LQG 控制器的主動(dòng)懸架對(duì)車輛行駛平順性和乘坐舒適性的改善有良好的效果。
