Filtering Structural Modes in Aircraft: Notch Filters Vs Kalman Filters
The disturbances to an airframe’s sensors caused by the flexibility of the airframe is called structural coupling. Notch filters are currently used to attenuate the effect that the structural modes have on the aircraft’s inertial flight control sensors. However, this approach is becoming more problematic with modern combat aircraft. A complex model which is representative of an agile combat air...
متن کاملKalman Filters
The Kalman Filter is a statistical method that involves an algorithm which provides an efficient recursive approach to estimatating the states of a process by minimizing the mean of the squared error. The filter is a powerful tool in statistical signal processing that allows for acurate estimations of past, present and future states, even with an incomplete or imprecise system model.
متن کاملSemi-G-filters, Stonean filters, MTL-filters, divisible filters, BL-filters and regular filters in residuated lattices
At present, the filter theory of $BL$textit{-}algebras has been widelystudied, and some important results have been published (see for examplecite{4}, cite{5}, cite{xi}, cite{6}, cite{7}). In other works such ascite{BP}, cite{vii}, cite{xiii}, cite{xvi} a study of a filter theory inthe more general setting of residuated lattices is done, generalizing thatfor $BL$textit{-}algebras. Note that fil...
متن کاملCertifying Kalman Filters
Formal code certification is a rigorous approach to demonstrate software quality. Its basicidea is to require that code producers provide formal certificates, or proofs, that their codesatisfies certain quality properties. In this paper, we focus on certifying software developed forstate estimation of dynamic systems, which is an important problem found in spacecraft, aircraft,g...
متن کاملSwitching Kalman Filters
We show how many di erent variants of Switching Kalman Filter models can be represented in a uni ed way, leading to a single, general-purpose inference algorithm. We then show how to nd approximate Maximum Likelihood Estimates of the parameters using the EM algorithm, extending previous results on learning using EM in the non-switching case [DRO93, GH96a] and in the switching, but fully observe...
