线性定常系统未知输入观测器设计--一个统一的框架

Unknown Input Observer Design for Linear Time-Invariant Systems -- A Unifying Framework

Markus Tranninger, Helmut Niederwieser, Richard Seeber, Martin Horn

摘要:

本文提出了一种新的线性时不变多变量系统的观测器设计方法。该设计基于到所谓的特殊坐标基的变换。这种形式揭示了重要的系统性质,如可逆性或有限和无限零结构。根据系统的强可观性属性,特殊的坐标基允许一个简单的未知输入观测器设计利用线性或非线性观测器设计技术。观测器设计方法的选择不仅取决于系统的性质,而且还取决于观测器的期望收敛行为。因此,所提出的设计过程可以被看作是一个统一的框架未知输入观测器的设计。

英文摘要:

This paper presents a new observer design approach for linear time invariant multivariable systems subject to unknown inputs. The design is based on a transformation to the so-called special coordinate basis. This form reveals important system properties like invertability or the finite and infinite zero structure. Depending on the system's strong observability properties, the special coordinate basis allows for a straightforward unknown input observer design utilizing linear or nonlinear observers design techniques. The chosen observer design technique does not only depend on the system properties, but also on the desired convergence behavior of the observer. Hence, the proposed design procedure can be seen as a unifying framework for unknown input observer design.
