Adaptive myriad filter with time-varying noise- and signal-dependent parameters
Радіоелектронні і комп'ютерні системи, 2022 The research subject of this article is the methods of locally adaptive filtering of non-stationary signals. The goal is to develop a locally-adaptive algorithm for non-stationary noise (from the viewpoint of its time-varying variance) suppression in ...

Adaptive observer design for time-varying nonlinear systems with unknown polynomial parameters [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2021 Many control methods involve the use of real-time values of the vector of state variables or its estimates. The article considers the problem of state variables observer design for a nonlinear non-stationary plant of a wider class compared to the known ...

GPI-repetitive control for linear systems with parameter uncertainty / variation
TecnoLógicas, 2015 Robust repetitive control problems for uncertain linear systems have been considered by different approaches. This article proposes the use of Repetitive Control and Generalized Proportional Integral (GPI) Control in a complementary fashion.

Estimation of time-space-varying parameters in dengue epidemic models
Communication in Biomathematical Sciences, 2017 There are nowadays a huge load of publications about dengue epidemic models, which mostly employ deterministic differential equations. The analytical properties of deterministic models are always of particular interest by many experts, but their validity

Numerical Study on Identification of Time Varying Parameters of Vibration Systems
Shock and Vibration, 1997 An on-line least squares algorithm has previously been successfully applied to linear vibration systems in order to identify time varying parameters. In this article the limitations of the approach and the factors affecting the identification are further
