Extended model of impaired cerebral autoregulation in preterm infants: Heuristic feedback control

Autor: Nikolai D. Botkin, Varvara L. Turova, Andrey E. Kovtanyuk, Irina N. Sidorenko, Renée Lampe

Publikováno v: Mathematical Biosciences and Engineering, Vol 16, Iss 4, Pp 2334-2352 (2019)

Cerebral autoregulation is the ability to keep almost constant cerebral blood flow (CBF) for some range of changing the mean arterial pressure (MAP). In preterm infants, this range is usually very small, even absent, and a passive (linear) dependence

Problem of radiation heat exchange with boundary conditions of the Cauchy type

Autor: Nikolai D. Botkin, Andrey E. Kovtanyuk, Alexander Yu. Chebotarev

Publikováno v: Communications in Nonlinear Science and Numerical Simulation. 75:262-269

In this paper, a quasi-static problem of radiative-conductive heat exchange in a three-dimensional domain is considered in the framework of diffusion P1 approximation of the radiation transfer equation. The peculiarity of the problem statement is tha

Continuum model of oxygen transport in brain

Autor: Alexander Yu. Chebotarev, Andrey E. Kovtanyuk, Nikolai D. Botkin, Varvara Turova, Renée Lampe, Irina Sidorenko

Publikováno v: Journal of Mathematical Analysis and Applications. 474:1352-1363

A continuum steady-state model of oxygen transport in the brain is studied. The unique solvability of the corresponding nonlinear boundary-value problem is proven. The convergence of a simple iterative procedure for finding solutions of the boundary-

Backstepping Control of Aircraft Take-Off in Windshear

Autor: Alexander P. Krishchenko, Nikolai D. Botkin, Alexey E. Golubev

Publikováno v: IFAC-PapersOnLine. 52:712-717

In this paper, we deal with the problem of aircraft take-off control in the presence of a windshear. A simplified point mass nonlinear model of aircraft dynamics assuming the flight in a vertical plane is used. A reference trajectory is constructed t

Aircraft Guiding in Windshear through Differential Game-Based Overload Control

Autor: Alexey E. Golubev, Nikolai D. Botkin, Varvara Turova

Publikováno v: IFAC-PapersOnLine. 52:706-711

The problem of aircraft take-off under windshear conditions is considered as a differential game. A simplified five-dimensional nonlinear model of aircraft dynamics, assuming the flight in a vertical plane, is used. The overloads, differences between

Optimal Disturbance Generation for Flight Control Law Testing

Autor: Nikolai D. Botkin, Johannes Diepolder, Florian Holzapfel

Publikováno v: IFAC-PapersOnLine. 52:730-734

In this paper we present an approach for testing flight control laws with optimal disturbances using differential game theory. The approach is based on a state constrained differential game formulation in which the criterion under investigation is in
