摘要
针对 1/4车辆模型 ,应用最优控制理论设计了主动悬架控制系统、半主动悬架控制系统 ,并通过计算机仿真对系统的控制性能进行了研究 ,对仿真结果进行了分析比较。结果表明 ,在模拟仿真及实际控制过程中 ,采取主动控制及半主动控制时应分别选取加权矩阵 ,以保证获得较好的减振效果 ,且半主动悬架同样有较好的减振效果 ,具有广泛的应用前景。
In this paper, the optimal control method is applied to design the active and semi active suspensions control system that based on a quarter car model. Computer simulation was used to study the control performance of the system. The computer simulation results were analyzed and compared. Simulation results indicate that active and semi active control will select different weighting matrix to acquire better vibration damping effect during the analogue simulation and realistic control. Semi active suspensions have similarly better vibration damping effect. The perspective of application is comprehensive.
