Feedback Control Method Using Haar Wavelet Operational Matrices for Solving Optimal Control Problems

, 2020
Most of the direct methods solve optimal control problems with nonlinear programming solver. In this paper we propose a novel feedback control method for solving for solving affine control system, with quadratic cost functional, which makes use of only ...

A Robust High-Order Haar Wavelet Collocation Method for Linear and Nonlinear Delay Differential Equations: Theoretical Analysis and Numerical Validation

Mathematical and Computational Applications
Delay differential equations form a distinct class of differential equations in which the derivative of the dependent variable depends on its value at an earlier time. This unique structure makes them particularly suitable for modeling phenomena in areas

The Wavelet-based Estimation for Long Memory Signal Plus Noise Models [PDF]

We propose new wavelet-based procedure to estimate the memory parameter of an unobserved process from an observed process affected by noise in order to improve the performance of the estimator by taking into account the dependency of the wavelet ...

Numerical Approach Based on the Haar Wavelet Collocation Method for Solving a Coupled System with the Caputo–Fabrizio Fractional Derivative

In the present paper, we consider an effective computational method to analyze a coupled dynamical system with Caputo–Fabrizio fractional derivative. The method is based on expanding the approximate solution into a symmetry Haar wavelet basis.

Higher order Haar wavelet collocation method for systems of integral-differential equations

In this thesis, the Haar Wavelet Collocation Method (HWCM) and its higher-order extension (HHWCM) are used to solve a coupled system of second-order integro-differential equations (IDEs) numerically in an efficient manner.
