采用两个自由度（1/4汽车模型）来评价备选线性控制律。所考虑的控制律有全状态反馈、簧载质量绝对速度反馈和采用悬架偏置作为测量的LQG调节器。结果表明，这三种方法都可以提高簧载质量的乘坐质量，但总体而言，使用悬架偏转的LQG调节器在乘坐质量、悬架包装和道路保持约束之间提供了最佳的权衡。
A two degree of freedom (1/4 car model) is used to evaluate alternative linear control laws. Control laws considered are full state feedback, sprung mass absolute velocity feedback and an LQG regulator using suspension defelection as the measurement. It is shown that all three can yield improvements to the sprung mass ride quality but that overall the LQG regulator using suspension deflection provides the best trade-off between ride quality, suspension packaging and road holding constraints.
