Robust Adaptive Tracking Control for Nonlinearly Parameterized High-Order Systems With Unmatched Disturbances

open access: yesIEEE Access, 2023
The output tracking problem for a class of nonlinearly parameterized high-order uncertain systems with unmatched disturbances is studied. The developed robust adaptive control scheme is based on the combination of a decoupled backstepping control method ...

Global Boundedness of the Gradient for a Class of Nonlinear Elliptic Systems [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2014
Gradient boundedness up to the boundary for solutions to Dirichlet and Neumann problems for elliptic systems with Uhlenbeck type structure is established. Nonlinearities of possibly non-polynomial type are allowed, and minimal regularity on the data and on the boundary of the domain is assumed.

Global boundedness to a 3D chemotaxis-Stokes system with porous medium cell diffusion and general sensitivity

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we will develop an analytical approach to construct the global bounded weak solutions to the initial-boundary value problem of a three-dimensional chemotaxis-Stokes system with porous medium cell diffusion Δnm\Delta {n}^{m} for m≥6563m ...

Logistic damping effect in chemotaxis models with density-suppressed motility

open access: yesAdvances in Nonlinear Analysis, 2022
This paper is concerned with a parabolic-elliptic chemotaxis model with density-suppressed motility and general logistic source in an n-dimensional smooth bounded domain with Neumann boundary conditions.

Longterm existence of solutions of a reaction diffusion system with non-local terms modeling an immune response—An interpretation-orientated proof

open access: yesPartial Differential Equations in Applied Mathematics, 2022
This paper shows the global existence and boundedness of solutions of a reaction diffusion system modeling liver infections. The existence proof is presented step by step and the focus lies on the interpretation of intermediate results in the context of ...

Global boundedness of the gradient for a class of Schrödinger equations [PDF]

open access: yesNonlinear Analysis: Theory, Methods & Applications, 2017
In this paper, via applying the method developed by A. Cianchi and V. Maz'ya, the author obtains the global boundedness of the gradient for solutions to Dirichlet and Neumann problems of a class of Schrödinger equations under the minimal assumptions for integrability on the data and regularity on the boundary of the domain.
