摘要

针对某汽车主动悬架系统,设计了一种基于7自由度整车模型的分散特征结构分配(EA)控制器。利用重叠分解,将全车模型分散到两个半车模型上。对于每一个半车模型,对于由重叠分解引起的扰动,通过分配系统的左特征结构,可以得到有效的抑制控制器。通过计算机仿真,比较了分散EA控制器与传统集中式EA控制器的性能。

Overlapping decentralized EA control design for an active suspension system of a full car model
A decentralized eigenstructure assignment (EA) controller is designed for an active suspension system of a vehicle based on a 7-degree of freedom full car model. Using overlapping decomposition, the full car model is decentralized by two half car models. For each half car model, for the disturbance which is caused by the overlapping decomposition, an effective suppressible controller can be obtained by assigning the left eigenstructure of the system. The performance of the decentralized EA controller is compared with that of a conventional centralized EA controller through computer simulations.
