液压主动悬架的非线性自适应控制

以车身垂直加速度和悬架动行程为控制目标，同时引入非线性高通滤波器和非线性低通滤波器，基于逆向递推(Backstepping)技术，并考虑液压系统的非线性特性及其参数不确定性，提出了一种主动悬架的非线性自适应控制方法。仿真结果表明，在不同的激励信号作用下，都取得了较好的控制效果。

Nonlinear Adaptive Control of Hydraulic Active Suspension

A dynamics model for vehicle active suspension(includin g hydraulic system)is set up.Consi dering the nonlinear feature and t he parameters uncertainty of the h ydraulic system,a nonlinear adapti ve control approach based on back- stepping technique is proposed to control the car body vertical acce leration and suspension travel via a low-pass nonlinear filter and a high pass nonlinear filter.The sim ulation results indicate that the control approach can greatly impro ve ride comfort and maneuvering pe rformance.
