摘要
利用ADAMS软件建立了带有汽车动力学控制(VDC)系统的整车多体动力学模型,在MATLAB环境中设计了PID控制的VDC系统,定义了MATLAB与ADAMS环境下车辆模型的数据交换接口,将整车模型与设计的控制系统在ADAMS/Car和MATLAB/Simulink环境下通过输入输出接口进行了联合仿真,研究了VDC系统的最佳控制参数,实现了几种行驶工况下的VDC系统及整车动态特性的仿真分析。仿真结果表明,所设计的横向稳定性控制器控制有效,实时性好,提高了汽车的操纵性能。
A VDC combined simulation model is presented based on the co-simulation technology in this article.First,by using ADAMS software,a multi-body dynamic vehicle model of a full vehicle is established,then a PID controller is designed for the vehicle dynamics control(VDC)system under MATLAB/Simulink environment.The data exchange interface with ADAMS is also defined.At last,the proposed controller is implemented with the multi-body dynamic model of a full vehicle in ADAMS.The co-simulations are carried out repeatedly until satisfactory control results are reached.The co-simulation model can simulate vehicle dynamic response with the control of VDC under various operating condition.As a result,it is very useful to speeding up the development of VDC system,and a kind of effective method for vehicle engineering is provided.
