| 摘 要： | 为了提高车辆的乘坐舒适性和改善操纵稳定性,以电子控制空气悬架为研究对象,应用PID控制理论,研制了调节空气弹簧刚度的可编程控制器(PLC),并设计了相应的控制程序。该控制器以空气悬架的刚度作为控制量,选取簧上质量垂直振动加速度均方根值为目标量,建立了1/4车辆悬架PID控制仿真模型,对PID控制系统进行仿真。仿真分析表明,PID控制算法可以改善汽车的行驶平顺性,对空气悬架的控制是可行且有效的。

Development of PID Control System for Electronically Controlled Air Suspension |

| Abstract: | In order to improve vehicle's comfort and handling stability,electronically controlled air suspension is taken as study object.Using PID control theory,PLC controller was designed,which can regulate stiffness of air spring,and the control program was also developed.Taking stiffness of air suspension as control variable,and the acceleration of the sprung mass as target values,one-quarter vehicle model of air suspension for simulating is established,then PID control system was simulated.The simulation results show that the PID control algorithm can improve vehicle ride performance,which is feasible and effective for controlling air suspension. |
