摘要
汽车半主动悬架系统的控制算法与策略决定半主动悬架系统的智能化程度和控制效果。应用汽车行驶动力学理论,建立二自由度1/4汽车磁流变半主动悬架的动力学模型,设计了半主动悬架最优控制器,提出基于磁流变减振器可调阻尼力的控制策略。以某款轿车前悬架参数为例,在Simulink软件中仿真分析半主动悬架系统的控制效果,结果表明,应用最优控制的汽车磁流变半主动悬架可以有效提高悬架性能。
The control algorithm and strategy of vehicle semi-active suspension system determines the degree of intelligence and control effect of semi-active suspension system. Based on system dynamics theory of vehicle, the dynamic model of 1/4 magnetorheological semi-active suspension with two degrees of freedom was established. The semi-active suspension optimal controller was designed, and the control strategy based on magnetorheological damper with adjustable damping force was put forward. Using the front suspension parameters of a vehicle, simulation analysis of the control effect had been done in the Simulink. The results show that the magnetorheological semi-active suspension system based on the optimal control of the vehicle can effectively improve the suspension performance.
