Active control of vibrant actuators with adaptive adjustment of the reference [PDF]
, 1999 An improved adaptive filter for eliminating periodic vibrations of unknown frequency in rotary machinery is presented. The proposed canceller is based on a usual bank of digital adaptive notch filters, each filter tuned in the cancellation of one ...

Adaptive parameters for tracking filters innovation system
Advances in Mechanical Engineering, 2016 One of the most important parts in target tracking is the filter algorithm. In the practical engineering, α-β-γ and α-β-γ-δ filters are often applied due to its simpler arithmetic operations.

A New Approach to Adaptive Signal Processing
, 2015 A unified linear algebraic approach to adaptive signal processing (ASP) is presented. Starting from just Ax=b, key ASP algorithms are derived in a simple, systematic, and integrated manner without requiring any background knowledge to the field ...

A novel robust interacting multiple model filter for manoeuvering target tracking
Electronics LettersA robust interacting multiple model approach is proposed to address the problem of accuracy and non‐Gaussian measurement noise in manoeuvering target tracking. The proposed approach introduces multiple fading factors into the prediction covariance matrix
