Nonlinear controllers for nonlinear systems with input nonlinearities

Proceedings of the 36th IEEE Conference on Decision and Control, 1999
The authors consider control systems of the type \[ \dot x= f(x,\sigma(u)),\quad x(0)= x_0,\quad t\geq 0, \] where \(\sigma\) denotes an input nonlinearity -- in many cases saturation -- and present a methodology for designing globally stabilizing nonlinear controllers.

Nonlinear photonic crystals: I. Quadratic nonlinearity

Waves in Random Media, 2001
Summary: We develop a consistent mathematical theory of weakly nonlinear periodic dielectric media for the dimensions one, two and three. The theory is based on the Maxwell equations with classical quadratic and cubic constitutive relations. In particular, we give a complete classification of different nonlinear interactions between Floquet-Bloch modes

Nonlinear structural modification and nonlinear coupling

Mechanical Systems and Signal Processing, 2014
Structural modification methods were proved to be very useful for large structures, especially when modification is local. Although there may be inherent nonlinearities in a structural system in various forms such as clearances, friction and cubic stiffness, almost all of the structural modification methods are for linear systems.

Nonlinear Spectroscopy

Science, 1972
Although nonlinear spectroscopy evolved slowly in its initial stages, it is now becoming an important new branch of atomic and molecular spectroscopy. A variety of phenomena are being observed for the first time, either in steady state or in transient behavior.

Nonlinear Analysis

2010
This is the lecture the author delivered before the ''XII Congresso della Unione Matematica Italiana'' held at the University of Perugia, Italy, in September 1983. The author starts with a particularly interesting exposition of various examples which illustrate the great relevance of nonlinear analysis in solving basic problems like those proposed by ...

Nonlinear Models of Clinical Judgment: Communal Nonlinearity and Nonlinear Accuracy

Psychological Science, 2001
Despite our intuition that representative expert judgments are highly nonlinear, previous studies have shown only little, if any, nonlinearity in such judgments. The current study presents a method for assessing nonlinearity in judgment that is based on estimating communal nonlinearity—the systematic nonlinearity shared by the community of judges. The

Nonlinear leastpth optimization and nonlinear programming

Mathematical Programming, 1977
Over the past few years a number of researchers in mathematical programming became very interested in the method of the Augmented Lagrangian to solve the nonlinear programming problem. The main reason being that the Augmented Lagrangian approach overcomes the ill-conditioning problem and the slow convergence of the penalty methods.
