基于ADAMS和MATLAB的联合控制系统的仿真

Study on Associated Control System Simulation Based on ADAMS and MATLAB Software

目前对车辆智能减振控制的研究基本上是通过建立其数学模型,然后利用MATLAB软件仿真,得到设计的控制器的最终减振效果。然而通过这种方式设计出来的控制器,在实际的应用中控制效果有很大的差别。ADAMS是美国MDI公司开发的非常优秀的机械系统动力学仿真分析软件,现已广泛地应用于汽车、机械制造业等领域,用它建立的系统虚拟模型能更接近实际的物理模型,这为以后的物理样机试验提供了更为可靠的依据。通过该软件建立了汽车1/4的2自由度悬架虚拟模型,利用ADAMS/CONTROL控制模块与MATLAB接口进行联合仿真,结果证实了该方法的实用性及可行性,为汽车悬架减振性能的开发设计提供了一种有效的现代化手段。

Up to now,the study of intelligent absorbed-shock control of vehicle is almost based on math-model, and then get the effects of the designed shock-absorber by MATLAB software. But the absorder designed by this means in practice can＇t get the good effect. ADAMS is very excellent software in automatic dynamic analysis of mechanical system ,now widely applied to the most field such as automobile, mechanism and so on. The virtual model created by ADAMS software is approaching the real model ,and it can provide the credible result for the real model test. In this paper, We simulated and controlled the 1/4 suspension system by using them. The result proves the method is practical and available, and provides efficient and modern tools for developing suspension system.
