Kalman Filter Design in Structural Identification with Unknown Excitation
Abstract—This article is about first step of structural health monitoring by identifying structural system in the presence of unknown input. In the structural system identification, identification of structural parameters such as stiffness and damping are considered. In this study, the Kalman filter (KF) design for structural systems with unknown excitation is expressed. External excitations, s...
متن کاملFrequency Domain System Identification When Assuming Unknown But Bounded Errors
This paper discusses the frequency domain system identification problem under the UBBE assumption. It demonstrates that the set of all possible identifications is a finite union of polyhedra. The paper also shows how the problem of finding one valid identification reduces to finding a feasible solution to a nonlinear system of equations under box constraints. An example of applying the resultin...
متن کاملFunctional dependencies distorted by errors
A relational database D is given with Ω as the set of attributes. We assume that the rows (tuples, data of one individual) are transmitted through a noisy channel (or, as many times in case of the datamining applications, the observed data is distorded from the real values in a manner which we cannot know). In case of low probability of the error it may be supposed that at most one data in a ro...
متن کاملAvoiding Approximation Errors in Multi-Issue Negotiation with Issue Dependencies
Searching for good bids in a utility space based on multiple, dependent issues in general is intractable. Tractable algorithms do exist for independent issue sets, so one idea is to eliminate the dependencies by approximating the more complex utility space with issue dependencies. It has been shown that an approximation may give reasonable results when some structural features of the negotiatio...
متن کاملFunctional Dependencies in Presence of Errors
A relational database D is given with Ω as the set of attributes. The rows (tuples, data of one individual) are transmitted through a noisy channel. It is supposed that at most one data in a row can be changed by the transmission. We say that A → b (A ⊂ Ω, b ∈ Ω) is an error-correcting functional dependency if the data in A uniquely determine the data in b in spite of the error. We investigate ...
