Abstract

This study develops a generalized $H_{2}$ observer to estimate the road profile in the semi-active automotive suspension system. The dynamics of the quarter-car model are represented in the descriptor nonlinear parameter-varying system framework, with the road profile as a system's state that is of arbitrary dynamics. Then, a road profile estimation method is designed by using a generalized $H_{2}$ observer, which utilizes the onboard accelerometers as the observer's input. The adverse impact of measurement noises on the accuracy of estimation results is alleviated via the generalized $H_{2}$ framework. The proposed observer is designed by solving an LMI-based constrained optimization problem. Frequency domain analysis and time domain simulations illustrate the efficiency of the proposed strategy.

用于汽车悬架系统路面轮廓估计的广义 H 2 观察器。

本研究开发了一种广义 H 2 观察器，用于估计半主动汽车悬架系统中的路面轮廓。四分之一汽车模型的动力学在描述符非线性参数变化系统框架中表示，路面轮廓作为系统的状态，具有任意的动力学特性。然后，使用广义 H 2 观察器设计了一种路面轮廓估计方法，该方法利用车载加速度计作为观察器的输入。通过广义 H 2 框架，测量噪声对估计结果准确性的不利影响得以缓解。所提出的观测器是通过解决基于 LMI 的约束优化问题而设计的。频域分析和时域仿真说明了拟议策略的效率。
