基于Matlab的车辆主动悬挂控制研究

Research on active vibration control technology for vehicle vibration based on matlab

建立了一个具有六自由度的客车横向振动力学模型及动力学运动方程,运用线性二次型最优控制方法,用MATLAB软件编写程序并计算出最优反馈矩阵K,并用Simulink进行了仿真计算及分析。结果表明采用主动悬挂技术可以有效改善车辆的横向振动性能。

A six-degree-of-freedom lateral full active suspension, the thesis constructed the state equations, then ed with MATLAB language vibration model is considered in this paper.In the research of dynamic equations of the simplified model and deduced the and computed the feedback gains using LQR method.From the analysis, the paper drew the conclusion that the full active suspension system could improve the lateral vibration characters of locomotive and car effectively.
