Characteristic Model-Based Adaptive Control for a Class of MIMO Uncertain Nonaffine Nonlinear Systems Governed by Differential Equations

Complexity, 2020
This paper addresses the difficulty of designing a controller for a class of multi-input multi-output uncertain nonaffine nonlinear systems governed by differential equations. We first derive the first-order characteristic model composed of a linear time-

Type-2 fuzzy linear systems [PDF]

, 2017
Fuzzy Linear Systems (FLSs) are used in practical situations where some of the systems parameters or variables are uncertain. To date, investigations conducted on FLSs are restricted to those in which the uncertainty is assumed to be modeled by Type-1 ...

Random and interval uncertain symplectic methods for linear Birkhoff equations and their comparison study [PDF]

SCIENTIA SINICA Physica, Mechanica & Astronomica, 2020
With the increasing complexity and design requirement of engineering structures, the numerical computation plays an increasingly important role in the structural analysis. The symplectic algorithm for Birkhoffian systems has advantages over the traditional algorithm in accuracy and stability, and general mechanical systems can be transformed into ...

Tracking Control of a Class of Fuzzy Dynamical Systems Under the Concept of Granular Differentiability

Fuzzy Information and Engineering, 2023
In this work, the tracking control of a class of uncertain linear dynamical systems is investigated. The uncertainty is considered to be represented as fuzzy numbers, and hence, these uncertain dynamical systems are referred to as fuzzy linear dynamical ...

Initial Value Estimation of Uncertain Differential Equations Based on Residuals with Application in Financial Market

Axioms
The initial value estimation of uncertain differential equations refers to the process of estimating the initial state of a time-varying system using observed data when we cannot know exactly the initial state of the system in uncertain environments.

Asymptotic Output-Feedback Stabilization of Linear Evolution Equations with Uncertain Inputs via Equivalent Control Method [PDF]

2018 IEEE Conference on Decision and Control (CDC), 2018
The paper studies the problem of minimax control design for linear evolution equations in Hilbert spaces with measurement noise and additive exogenous disturbances. The key result of the paper is an algorithm, generating a control in an output-feedback form, which steers the state of the system as close as possible to a given sliding hyperplane ...
