| 摘 要： | 将线性二次型高斯控制（LQG）的理论应用到了车辆半主动悬架系统的控制中，通过仿真分析了其特性，LQG控制的半主动悬架系统，在悬架弹性元件支撑的所有部件的质量（简称簧上质量）的固有频率附近，悬架的平顺性和动挠度不能同时得到改善，而在中频段可以使二者同时得到改善，在低频段和接近非簧载质量的固有频率段内，改善悬架的平顺性则必然会增加悬架的动挠度．

| Abstract: | In this study, the linear quadratic Gauss（LQG） control theory is preliminarily applied for semiactive vehicle suspension system control. Through simulation analysis on system properties, the improvement conflict between driving comfort and dynamic deflection is thereafter detected close to innate frequency of spring-loading quality, except for medium frequency bands. In conclusion, within low frequency bands and near innate frequency band of non-spring-loading quality, the improvement for driving comfort will increase the dynamic deflection. |
