基于内模原理的汽车主动悬挂系统的减振控制

摘要

The problem of vibration control for vehicle active suspension systems under road roughness disturbance is considered. Firstly, the model for one-degree-freedom quarter-car suspension systems is simplified and a model road roughness disturbance is presented. Then, the control structure for vehicle active suspension systems is proposed by using the internal model principle. A vibration control law is designed by using the pole placement approach. Numerical simulations illustrate the effectiveness of the vibration control law.%研究路面粗糙度扰动作用下的汽车主动悬挂系统的减振控制问题.首先简化单自由度四分之一悬挂系统模型,建立路面粗糙度扰动模型.然后基于内模原理设计汽车主动悬挂系统的减振控制结构,并利用线性系统的极点配置方法设计系统的减振控制律.最后利川数字仿真验证了减振控制律的有效性.
