Optimal V-Plane Robust Stabilization Method for Interval Uncertain Fractional Order PID Control Systems

open access: yesFractal and Fractional, 2021
Robust stability is a major concern for real-world control applications. Realization of optimal robust stability requires a stabilization scheme, which ensures that the control system is stable and presents robust performance for a predefined range of ...

An Uncertain Data Integration System [PDF]

open access: yes, 2012
Data integration systems offer uniform access to a set of autonomous and heterogeneous data sources. An important task in setting up a data integration system is to match the attributes of the source schemas. In this paper, we propose a data integration system which uses the knowledge implied within functional dependencies for matching the source ...

Resilient Observer-Based H Control of Uncertain Nonlinear Networked Control Systems

open access: yesIEEE Access, 2021
This paper considers the resilient $H_{\infty }$ dynamic control of nonlinear uncertain systems over a network assuming random communication packet dropouts, a subject which is seldom considered in the current literature for such uncertain systems. The

High Gain Observer Based Active Disturbance Estimation ADE for Second Order Nonlinear Uncertain Systems (ex:Induction Motor)

open access: yesEngineering Proceedings, 2023
The main objective of this paper is to solve state observation and external disturbances estimation for a class of second-order nonlinear systems. The proposed method relies mainly on the high gain observer as an estimator that tries to estimate the ...

Design of time-varying input-to-state stability tracking control Lyapunov functions for disturbance attenuation

open access: yesSICE Journal of Control, Measurement, and System Integration, 2021
In this study, we address limitations of the existing methods of disturbance attenuation for nonlinear control systems. We focus on scenarios with trajectory tracking in differentially flat systems.

Design of adaptive intuitionistic fuzzy controller for synchronisation of uncertain chaotic systems

open access: yesCAAI Transactions on Intelligence Technology, 2020
This study presents the synchronisation between two non-linear Lorenz chaotic systems using an adaptive intuitionistic fuzzy controller (AIFC). This problem is solved in the presence of external disturbances and uncertainties.

A Chattering-Reduction Sliding Mode Control Algorithm for Affine Systems With Input Matrix Uncertainty

open access: yesIEEE Access, 2022
This paper aims to develop a chattering-reduction sliding mode control (SMC) approach for affine systems with input matrix uncertainty. Input matrix uncertainty poses adverse effects on systems, such as aggravating the chattering effect, and even causing

Transient and stability analysis of heterogeneous micro-grid networks subject to uncertainties

open access: yesIET Smart Grid, 2020
In this study, networks of interconnected heterogeneous micro-grids are studied. The transient dynamics is modelled as an averaging process whereby micro-grids are assimilated to dynamic agents in a network.

Further results on delay-dependent robust H∞ control for uncertain systems with interval time-varying delays

open access: yesSystems Science & Control Engineering, 2021
This work focuses on the delay-dependent robust H∞ control for uncertain linear systems with interval time-varying delays. The key features of the method include employment of a tighter integral inequality and construction of an appropriate Lyapunov ...
