摘要
根据已建立的1/2车体动力学模型和单轨路面输入模型,设计车辆主动悬架的线性二次型高斯(LQG)最优控制器,利用MATLAB/SIMULINK软件构建路面输入仿真模型和1/2车体仿真模型.结果分析证实,具有LQG控制器的主动悬架可以改善车辆的运行性能.
Linear-Quadratic-Gaussian （LQG） controller of vehicle active suspension is designed based on a 1/2 car model and a road input model. By using MATLAB/SIMULINK software, their simulation model are established. The results indicate that the vehicle driving performance can be improved on account of active suspension with a LQG controller.
