What is field theory?

JL Martin - American journal of sociology, 2003 - journals.uchicago.edu
Field theory is a more or less coherent approach in the social sciences whose essence is
the explanation of regularities in individual action by recourse to position vis-à-vis others …

[图书][B] Control and nonlinearity

JM Coron - 2007 - books.google.com
This book presents methods to study the controllability and the stabilization of nonlinear
control systems in finite and infinite dimensions. The emphasis is put on specific phenomena …

Tracking control for boundary controlled parabolic PDEs with varying parameters: Combining backstepping and differential flatness

T Meurer, A Kugi - Automatica, 2009 - Elsevier
The combination of backstepping-based state-feedback control and flatness-based
trajectory planning and feedforward control is considered for the design of an exponentially …

Robust state-feedback stabilization of an underactuated network of interconnected n+ m hyperbolic PDE systems

We detail in this article the development of a delay-robust stabilizing state feedback control
law for an underactuated network of two subsystems of heterodirectional linear first-order …

Exact boundary controllability of 1-D parabolic and hyperbolic degenerate equations

M Gueye - SIAM Journal on Control and Optimization, 2014 - SIAM
The boundary controllability of a class of one-dimensional degenerate equations is studied
in this paper. The novelty of this work is that the control acts through the part of the boundary …

Backstepping and flatness approaches for stabilization of the stick-slip phenomenon for drilling

C Sagert, F Di Meglio, M Krstic, P Rouchon - IFAC Proceedings Volumes, 2013 - Elsevier
In this article, we propose control solutions to suppress undesirable torsional oscillations of
the drill string in oil well drilling systems. Two feedback control laws are derived from Partial …

Robust output feedback stabilization of an ODE–PDE–ODE interconnection

F Di Meglio, PO Lamare, UJF Aarsnes - Automatica, 2020 - Elsevier
We propose a controller that robustly stabilizes an interconnection of Ordinary Differential
Equations with two hyperbolic linear Partial Differential Equations. The proposed design …

A backstepping approach to output regulation for coupled linear wave–ODE systems

J Deutscher, J Gabriel - Automatica, 2021 - Elsevier
This paper is concerned with the output regulation problem for coupled wave–ODE systems
subject to spatially-varying coefficients. This problem is traced back to the regulator design …

A simultaneous space‐time discretization approach to the inverse dynamics of geometrically exact strings

T Ströhle, P Betsch - International Journal for Numerical …, 2022 - Wiley Online Library
A continuous space‐time Galerkin method is newly proposed for the numerical solution of
inverse dynamics problems. The proposed space‐time finite element method is combined …

Control of 2× 2 linear hyperbolic systems: Backstepping-based trajectory generation and PI-based tracking

PO Lamare, N Bekiaris-Liberis - Systems & Control Letters, 2015 - Elsevier
We consider the problems of trajectory generation and tracking for general 2× 2 systems of
first-order linear hyperbolic PDEs with anti-collocated boundary input and output. We solve …
