On the Global Convergence of a Filter--SQP Algorithm

open access: yesSIAM Journal on Optimization, 2002
A mechanism for proving global convergence in sequential quadratic programming (SQP) filter methods for nonlinear programs is described. The proposed algorithm contains a convergent inner iteration for calculating a suitable trust region radius.

On Stability and Convergence of Distributed Filters [PDF]

open access: yesIEEE Signal Processing Letters, 2021
Recent years have bore witness to the proliferation of distributed filtering techniques, where a collection of agents communicating over an ad-hoc network aim to collaboratively estimate and track the state of a system. These techniques form the enabling technology of modern multi-agent systems and have gained great importance in the engineering ...

Performance analysis of SMI filter for antenna array receiver in pulse interference environment

open access: yesFrontiers in Physics, 2023
This paper analyzes the performance of sample matrix inversion (SMI) filter used by antenna array receivers in pulse interference environment. Firstly, from the perspective of comparison, it is proved that the theoretical optimal signal to interference ...

Modified Proportionate Affine Projection Algorithm Based Adaptive DSTATCOM Control With Increased Convergence Speed

open access: yesIEEE Access, 2022
The three-phase DSTATCOM is prone to higher dynamics due to grid disturbances. The proportionate affine projection algorithm (PAPA) is an adaptive filter that can be used for DSTATCOM control.

On the convergence of the ensemble Kalman filter [PDF]

open access: yesApplications of Mathematics, 2011
Convergence of the ensemble Kalman filter in the limit for large ensembles to the Kalman filter is proved. In each step of the filter, convergence of the ensemble sample covariance follows from a weak law of large numbers for exchangeable random variables, the continuous mapping theorem gives convergence in probability of the ensemble members, and $L^p$

Kernel Adaptive Filtering Prediction Algorithm of Chaotic Time Series [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban, 2023
In practical environment, chaotic time series often contain a lot of noise and outliers. Because of these interference factors, the prediction performance of the kernel adaptive filter based on the second-order similarity measure could decrease ...

L-filters and L-filter convergence [PDF]

open access: yesInternational Journal of Fuzzy Logic and Intelligent Systems, 2009
In this paper, we study the relations between L-fuzzy topologies and L-filters on a strictly two-sided, commutative quantale lattice L. We define an L-fuzzy neighborhood filter and introduce the notion of L-filter convergence in L-fuzzy topological spaces.

Superlinear Convergence and Implicit Filtering [PDF]

open access: yesSIAM Journal on Optimization, 2000
Summary: We show how the implicit filtering algorithm can be coupled with the BFGS quasi-Newton update to obtain a superlinearly convergent iteration if the noise in the objective function decays sufficiently rapidly as the optimal point is approached.

Prediction Error Method (PEM)-Based Howling Cancellation in Hearing Aids: Can We Do Better?

open access: yesIEEE Access, 2023
This work develops an effective technique acoustic feedback cancellation (AFC) in the digital hearing aid (DHAid) devices. The normalized least mean square (NLMS) algorithm-based AFC method may suffer from a biased convergence.

Noise control with Kalman filter for active headrest

open access: yesXibei Gongye Daxue Xuebao, 2021
A control strategy with Kalman filter (KF) is proposed for active noise control of virtual error signal for active headset. Comparing with the gradient based algorithm, KF algorithm has faster convergence speed and better convergence performance. In this
