Linear Matrix Inequality‐based design of distributed proportional‐integral‐derivative for the output consensus tracking in heterogeneous high‐order multi‐agent systems

Asian Journal of Control, EarlyView.
Abstract This article addresses the cooperative output consensus tracking problem for high‐order heterogeneous multi‐agent systems via a distributed proportional‐integral‐derivative (PID)‐like control strategy and proposes two novel control methodologies for the tuning of the control gains, which do not require any assumption and/or limitation on agent

Depth functions based on a number of observations of a random vector [PDF]

We present two statistical depth functions given in terms of the random variable defined as the minimum number of observations of a random vector that are needed to include a fixed given point in their convex hull.

Adaptive event‐based asynchronous approach for containment control of Markov jump multi‐agent systems with hidden Markov models

Asian Journal of Control, EarlyView.
Abstract This paper focuses on the issue of adaptive event‐triggered containment control for Markov jump multi‐agent systems characterized by hidden Markov jump parameters. The central objective is to design an output‐feedback controller for the Markov jump multi‐agent system by using an adaptive event‐triggered technique that not only ensures the ...

Winding number criterion for the origin to belong to the numerical range of a matrix on a loop of matrices

Mathematics Open
The numerical range of a matrix is a compact convex set in the complex plane that contains the convex hull of the spectrum of the matrix. A key question is whether the origin belongs to the convex hull of the spectrum or the numerical range.

A cone theoretic Krein-Milman theorem in semitopological cones [PDF]

Sahand Communications in Mathematical Analysis, 2018
In this paper, a Krein-Milman  type theorem in $T_0$ semitopological cone is proved,  in general. In fact, it is shown that in any locally convex $T_0$ semitopological cone, every convex compact saturated subset is the compact saturated convex hull of ...

Random volumes in d-dimensional polytopes

Discrete Analysis, 2020
Random volumes in d-dimensional polytopes, Discrete Analysis 2020:15, 17 pp. This paper concerns the following general question. Given a convex body $X$ in $\mathbb R^d$, how many points do you need to choose at random from inside $X$ before with high ...

Effect of Trimethylamine‐N‐Oxide (TMAO) and Sorbitol on the Catalytic Activity of Candida boidinii Formate Dehydrogenase

ChemCatChem, EarlyView.
The effects of the osmolytes TMAO and sorbitol on the catalytic activity of Candida boidinii formate dehydrogenase are investigated using computational and experimental studies. The osmolytes exert different effects on the inter‐domain fluctuations, solvation, and active site dynamics of the enzyme as well as on the substrate residence times.
