摘要
在ADAMS/Car下建立了前、后悬架都装有主动横向稳定杆的95自由度虚拟整车模型。采用模糊PID控制策略,在MATLAB/Simulink环境中对车辆抗侧倾性能进行了联合仿真,实现了PID控制过程中参数的在线整定。仿真结果表明,模糊PID控制具有较强的自适应能力和抗干扰能力,可有效减小车身侧倾角,在保证乘坐舒适性的同时提高了车辆的行驶稳定性。
A virtual car model is built by using ADAMS/Car.The model which equipped with active anti-roll bars in front and rear suspension is simplified with 95 DOFs.Based on the Matlab/Simulink software environment,a fuzzy PID control strategy is used to co-simulate vehicle anti-roll performance,and parameters in-line setting in the process of control is realized.The simulation results show that this fuzzy PID control has the ability of self-adjusting and decreasing the body roll angle effectively.The vehicle riding comfort is ensured and the vehicle handling stability is improved.
