A Variable Step-size CLMS Algorithm and Its Analysis [PDF]

Radioengineering, 2020
In this paper, a hyperbolic tangent variable step-size convex combination of the least mean square (HTVSCLMS) algorithm is proposed and analyzed. This work avoids the compromise between the convergence speed and the steady-state error for two filters in ...

On the Convergence of Constrained Particle Filters

IEEE Signal Processing Letters, 2017
The power of particle filters in tracking the state of nonlinear and non-Gaussian systems stems not only from their simple numerical implementation but also from their optimality and convergence properties. In particle filtering, the posterior distribution of the state is approximated by a discrete mass of samples, called particles, that stochastically

On n-Convergence of Filters

Al-Qadisiyah Journal of Pure Science, 2021
In this work, we have present a new form of sets named - open sets. We have study and described some of the properties and  relationships between these sets. We have obtained some results and relationships between by the theories inferring through the style set (n-open).

Grid-Tied Distribution Static Synchronous Compensator for Power Quality Enhancement Using Combined-Step-Size Real-Coefficient Improved Proportionate Affine Projection Sign Algorithm

Energies, 2021
A control structure design of a three-phase three-leg four-wire grid-tied Distribution Static Synchronous Compensator (DSTATCOM) based on a combined-step-size real-coefficient improved proportionate affine projection sign algorithm (CSS-RIP-APSA) has ...

Abstract Theorems on Exchange of Limits and Preservation of (Semi)continuity of Functions and Measures in the Filter Convergence Setting

Journal of Function Spaces, 2016
We give necessary and sufficient conditions for exchange of limits of double-indexed families, taking values in sets endowed with an abstract structure of convergence, and for preservation of continuity or semicontinuity of the limit family, with respect

Estimation of Power System and Electrical Transient Status Based on Particle Filter

Chemical Engineering Transactions, 2017
In order to improve the accuracy and convergence speed of the transient estimation of the power system, taking into account the nonlinearity of the system, the Kalman filter (EKF) algorithm which is mainly used in the current status estimation of the ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

A Generalized Gradient Projection Filter Algorithm for Inequality Constrained Optimization

Journal of Applied Mathematics, 2013
A generalized gradient projection filter algorithm for inequality constrained optimization is presented. It has three merits. The first is that the amount of computation is lower, since the gradient matrix only needs to be computed one time at each ...

Newton-Based Extremum Seeking for Dynamic Systems Using Kalman Filtering: Application to Anaerobic Digestion Process Control

Mathematics, 2023
In this paper, a new Newton-based extremum-seeking control for dynamic systems is proposed using Kalman filter for gradient and Hessian estimation as well as a stochastic perturbation signal with time-varying amplitude.
