Boundary Controllability and Observability of a Viscoelastic String [PDF]

open access: yes, 2012
In this paper we consider an integrodifferential system, which governs the vibration of a viscoelastic one-dimensional object. We assume that we can act on the system at the boundary and we prove that it is possible to control both the position and the ...

Multiobjective process controllability analysis [PDF]

open access: yes, 2004
A new approach for process controllability analysis by using multiobjective optimisation techniques is proposed. Within the approach, a set of performance specifications, such as minimum control error and input effort with closed-loop pole placement are ...

Controllability of networks: influence of structure and memory [PDF]

open access: yes, 2023
openIn this work we borrow some ideas from the the theory of lifted Markov chains, which can accelerate convergence of random walks algorithms thanks to the introduced memory effects, and apply them to the control of networks of dynamical systems ...

Interconnection topologies for multi-agent coordination under leader–follower framework [PDF]

open access: yes, 2009
In this paper, the formation control problem of the network of multiple agents is studied in terms of controllability, where the network is of the leader–follower structure with some agents taking leaders role and others being followers interconnected ...

Linked patterns of symptoms and cognition with brain controllability in major depressive disorder

open access: yesEuropean Psychiatry, 2023
Introduction Major depressive disorder (MDD) is characterized by both clinical symptoms and cognitive deficits. Prior studies have typically examined either symptoms or cognition correlated with brain measures, thus causing a notable paucity of stable ...

Lack of controllability of the heat equation with memory [PDF]

open access: yes, 2012
We consider a model for the heat equation with memory, which has infinite propagation speed, like the standard heat equation. We prove that, in spite of this, for every T > 0 there exist square integrable initial data which cannot be steered to hit zero ...

Controllability of linear impulsive systems – an eigenvalue approach [PDF]

open access: yes, 2020
summary:This article considers a class of finite-dimensional linear impulsive time-varying systems for which various sufficient and necessary algebraic criteria for complete controllability, including matrix rank conditions are established.

Analysis of the Effect of Degree Correlation on the Size of Minimum Dominating Sets in Complex Networks. [PDF]

open access: yesPLoS ONE, 2016
Network controllability is an important topic in wide-ranging research fields. However, the relationship between controllability and network structure is poorly understood, although degree heterogeneity is known to determine the controllability. We focus

Null-controllability, exact controllability, and stabilization of hyperbolic systems for the optimal time [PDF]

open access: yes, 2020
In this paper, we discuss our recent works on the null-controllability, the exact controllability, and the stabilization of linear hyperbolic systems in one dimensional space using boundary controls on one side for the optimal time.

Controllability of semilinear stochastic integrodifferential systems [PDF]

open access: yes, 2007
summary:In this paper we study the approximate and complete controllability of stochastic integrodifferential system in finite dimensional spaces. Sufficient conditions are established for each of these types of controllability.
