On relationships between two linear subspaces and two orthogonal projectors

open access: yesSpecial Matrices, 2019
Sum and intersection of linear subspaces in a vector space over a field are fundamental operations in linear algebra. The purpose of this survey paper is to give a comprehensive approach to the sums and intersections of two linear subspaces and their ...

On Positive Realness for Stochastic Hybrid Singular Systems

open access: yesIEEE Access, 2020
This paper deals with the problem of passivity analysis and passivity-based synthesis for continuous-time stochastic hybrid singular systems (SHSSs). First, a set of linear matrix inequalities for the stochastic admissibility and passivity, which is also

A New Stability Criterion for Systems with Distributed Time-Varying Delays via Mixed Inequalities Method

open access: yesComplexity, 2020
This paper is concerned with the delay-dependent stability of systems with distributed time-varying delays. The novelty relies on the use of some new inequalities which are less conservative than some existing inequalities.

Data-Driven Stabilization: A Robust Control Approach with Linear Matrix Inequalities

open access: yesSir Syed University Research Journal of Engineering and Technology
In this paper, we present a novel data-driven approach to stabilize discretized batch reactor systems under the influence of noisy data. By leveraging the framework of Linear Matrix Inequalities (LMIs), our method eliminates the need for explicit system

Further inequalities for convex functions with applications to matrix inequalities

open access: yesDemonstratio Mathematica
Building on the ideas and techniques from a recent paper by D.Q. Huy et al. [Linear Algebra Appl. 656 (2023), 368–384], we establish new inequalities for convex and log-convex functions.

Automatic tuning of paper machines cross-direction controllers via linear matrix inequalities

open access: yesJournal of Electrical Systems and Information Technology, 2015
The paper machine cross-direction (CD) process is a large-scale spatially distributed system. It is known to be severely ill-conditioned as the gain rolls down to zero for some of the process directions.

Robust Stabilization of Stochastic Markovian Jump Systems with Distributed Delays

open access: yesComplexity, 2021
This paper addresses the robust stabilization problem for a class of stochastic Markovian jump systems with distributed delays. The systems under consideration involve Brownian motion, Markov chains, distributed delays, and parameter uncertainties. By an
