Title

Neural networks-based state estimation

Abstract

State estimation of a dynamical system refers to estimating the state of a system given a model, measurements, and some information about the initial state. While Kalman filtering [1] does optimal state estimation of linear systems, optimal estimation of high order non-linear systems of ordinary differential equations is still an open problem. The research focuses on providing an optimal method for state estimation of such high order systems by using advancements in the field of data. We propose to use deep learning to estimate the state of a system and test our codes on discretization of systems of high-order ordinary differential equations derived from partial differential equations such as Kuramoto-Sivashinsky equation [2],wave equation [3] [4]and cantilevered Euler Bernoulli beam [5], [6]
