摘要
利用adams/car建立客车整车动力学模型,通过汽车横摆动力学分析建立理想状态下二自由度车辆参考模型。在分析了差动制动的车辆稳定性控制原理基础上,通过matlab/simulink构建以横摆角速度实际值与理想值的偏差值为控制变量的模糊PID反馈控制系统,通过adams/car和matlab联合仿真结果显示:经过控制后,客车侧滑得到了明显的抑制,车辆的轨迹追踪性能也得到了增强,客车操纵性和稳定性都得到了较好的改善。
The bus dynamics model is built by adams/car. 2--DOF ideal vehicle model under the reasonable conditions is established through the yawing dynamic analysis. Based on the analysis of the vehicle stability control principle with differential braking, the matlab/simulink is used to build the fuzzy PID feedback control system with the control variable of deviation value between actual yaw rate and ideal yaw rate. The joint simulation results of adams/car and matlab show that the sideslip is obviously inhibited, the trajectory tracking capacity is enhanced and the handling and stability of the bus are welt improved.
