摘要
建立整车悬架与电动助力转向集成动力学模型,并设计LQG最优控制器。通过在Matlab/Simulink环境下进行仿真运算,其结果表明,采用所提出的控制策略,不仅使汽车的侧倾角速度、悬架动挠度和轮胎动位移有所改善,而且使车辆的行驶平顺性、操纵稳定性有所提高。
The paper set up an integrated dynamics model of suspension and electrical power steering system, and designed a LQG controller based on the model, simulation is done under Matlab/Simulink and the results show that the control scheme can improve pitch angular ve- locity, suspension deflection, tire dynamic displacement and improve vehicle ride comfort and maneuverability.
