A Unified Approach of Controller Design and System Identification for Optimal Control of Single-Input Nonlinear Systems

open access: yesSICE Journal of Control, Measurement, and System Integration, 2018
This paper presents a novel unified approach of controller design and identification for unknown input affine nonlinear systems. An issue with obtaining the best performance of optimal control is that identification errors degrade control performance ...

Rule-Based Identification of Individuals with Mild Cognitive Impairment or Alzheimer’s Disease Using Clinical Notes from the United States Veterans Affairs Healthcare System

open access: yesNeurology and Therapy, 2023
Background Early identification of individuals with mild cognitive impairment (MCI) and Alzheimer’s disease (AD) is a clinical and research imperative. Use of diagnostic codes for MCI and AD identification has limitations.

Structural damping identification based on an iterative regularization method [PDF]

open access: yes, 2011
A time domain structural damping identification method is presented in this paper. The damping of a structure is assumed to be time-invariant Rayleigh damping, time-variant Rayleigh damping and modal damping, respectively, and an iterative regularization

Iterative Snapping of Odometry Trajectories for Path Identification [PDF]

open access: yes, 2014
An increasing number of mobile devices are capable of automatically sensing and recording rich information about the surrounding environment. Spatial locations of such data can help to better learn about the environment. In this work, we address the problem of identifying the locations visited by a mobile device as it moves within an indoor environment.

Two modified least-squares iterative algorithms for the Lyapunov matrix equations

open access: yesAdvances in Difference Equations, 2019
In this paper two modified least-squares iterative algorithms are presented for solving the Lyapunov matrix equations. The first algorithm is based on the hierarchical identification principle, which can be viewed as a surrogate of the least-squares ...

Least squares-based iterative identification methods for linear-in-parameters systems using the decomposition technique [PDF]

open access: yes, 2016
By extending the least squares-based iterative (LSI) method, this paper presents a decomposition-based LSI (D-LSI) algorithm for identifying linear-in-parameters systems and an interval-varying D-LSI algorithm for handling the identification problems of ...
