【摘要】 近年来联合仿真技术在车辆控制系统的开发研究中得到了广泛的应用。以某皮卡车为研究对象,首先利用ADAMS/CAR软件建立车辆多体动力学模型;然后在Matlab/Simulink环境中设计了基于自适应模糊PID控制的ASS,定义了与ADAMS/CAR环境下车辆模型的数据交换接口;最后,将设计的控制系统在ADAMS/CAR和Matlab/Simulink环境下通过输入输出接口进行联合仿真。文中对随机路面输入和脉冲路面输入工况下的ASS系统及整车动态特性进行了联合仿真研究,其研究结果为联合仿真技术在车辆工程中的实际应用提供了参考。更多还原

【Abstract】 The design process of controller for active suspension employed was proposed by an pickup vehicle based on the co-simulation.First,a detailed multi-body dynamic model of the vehicle was established by using ADAMS/CAR software package;Second,an Adaptive Fuzzy PID controller was designed for active suspension system and worked out by means of MATLAB/SIMULINK,the proposed control algorithm was integrated with the multi-body dynamic vehicle model and the co-simulations could be performed repeatedly until a satisfactory controller is achieved. The co-simulation model could simulate vehicle dynamic response with the control of ASS under pulse road and random road. As a result,it is very useful to speed up the development of ASS system,and a kind of effective method for vehicle engineering was provided.更多还原
