一种实用的半主动悬架的控制规律研究

Research on a Practical Control Strategy of Semi-active Suspension

文中主要研究以提高平顺性为主要目的的可变阻尼控制系统.在进行理想阻尼力的最优挂制过程中，采用了一种简单低成本的控制策略即由Karnoppe提出的天棚阻尼控制模型[1].其连续型控制策略是基于开关式阻尼控制策略[2]，但又避免了开关式的缺点，且其结构参数随路面级别的不同而不同.通过时域和领域计算可见这种控制方法的有效性.

The object of this article is to analyze the ideal damping control for vehicle suspension systems using optimal control strategy and to introduce another control strategy called Skyhook model proposed by D. Karnopp.Continuously damping control is based on on-off switching system, and its variable control gain depends on various road conditions. Using computer simulation, effectiveness of this system is evident and the possibility of this ride comfort improvement is verified by using this control.
