摘要
研究安装可控阻尼减振器的某履带式车辆悬架系统性能指标中的各被控量在3种加权系数组合下LQG控制的性能.根据悬架系统的物理约束条件及台架实验,提出了一种模糊控制规则的产生方法,并以此构成模糊控制器,进行了仿真研究.通过与被动悬挂及LQG控制的比较,证明该模糊控制策略在充分利用动行程空间的情况下,可以更有效地减小振动加速度.
Performances of LQG control under three kinds of combinations of weighting coefficients for a semi-active suspension of tracked vehicle are studied. The fuzzy control rules for the semi-active suspension system are presented based on the dynamics equations and rig experiments. Simulation results illustrate that fuzzy logic control minimizes the vertical acceleration effectively when compared with LQG control under the constraint on the suspension travels.
