摘要
建立了4自由度主动悬架车辆动力学模型,设计了主动悬架的最优控制数学模型,并使用Matlab/Simulink对加权系数对车身振动的影响进行了分析和优化,使主动悬架的控制效果得到大幅改善.
The 4-DOF vehicle dynamics model with active suspension is established, based on which the optimal control is designed. The rule how weight coefficients affect vehicle body＇ s vibration is analysed by Matlob Simulink. Weight coefficients are optimized, and the performance of active suspension is much better than before.
