Semi-Active Augmented H(subscript ∞) Control of Vehicle Suspension Systems with MR Dampers
半主動式懸吊系統磁流變減振器擴張式H(下標 ∞)控制器
摘要
本文探討並延伸H(下標 ∞)控制器應用於車輛懸吊系統磁流變阻尼器上。該控制器在閉迴路系統擔任系統控制器，提供有系統所需強健性。然為使磁流變阻尼器控制器能準確追蹤由系統控制器所發出期望阻尼力，吾人提出一過濾器。數值模擬證明本文所提出控制器具有良好性能，及工程實用性。

In this work, we extend and study the implementation of H(subscript ∞) output feedback controller to a vehicle suspension system with magnetorheological fluid (MRF) damper. In the closed-loop suspension system, the H(subscript ∞) controller serves as a system controller to provide the necessary robustness, however, in most of the cases, the controller gain is high. This makes the damper controller, which issues input currents to control the MR damper, hard to track the desired damping force. To this end, an augmented filter is proposed to remedy this issue. Although in the augmented filter, full system states are required in one of the term, while through numerical experiments, we found that this term can be ignored without sacrificing noticeable performance
