摘要
本文采用系统性能分析和Monte-Carlo方法,对线性最优控制主动悬架系统作了鲁棒稳定性研究。研究表明,指标的权重系数、状态测量方式、簧上质量和悬架刚度对系统的鲁棒稳定性有重要影响,而作动器和传感器的动态环节则对其影响不大。利用LTR方法,可以对LQG系统进行鲁棒稳定性恢复,同时使系统的性能损失减到最低限度。
In this paper, the stability robustness of linear optimal active suspension system is studied by using system performance analysis and Monte-Carlo method. The result indicates that system' s stability robustness is seriously affected by weighting coefficients, status measuring manner, sprung mass and suspension stiffness, but is less sensitive to dynamics of actuators and sensors, With LTR method, the stability robustness of LQG system can be recovered without seriously deteriorating the system's performance.
