Nonlinear learning control for a class of nonlinear systems
Automatica, 2001A nonlinear learning control scheme for asymptotic stabilization of a class of cascaded nonlinear systems is proposed. The direct Lyapunov method is one of the essential steps in the method. An illustrative example is provided.

Equivalent nonlinearization of nonlinear systems to random excitations
Probabilistic Engineering Mechanics, 1991The broadest class of solvable reduced Fokker-Planck equation is given and a new equivalent nonlinear method is presented to obtain an approximate probability density function for the response of a nonlinear oscillator to Gaussian white noise excitations. The method is based on the least meansquare criterion and Euler equation.

Expansions for Nonlinear Systems*
Bell System Technical Journal, 1982In this paper we study operator-type models of dynamic nonlinear physical systems, such as communication channels and control systems. Attention is focused on the problem of determining conditions under which there exists a power-series-like expansion, or a polynomial-type approximation, for a system's outputs in terms of its inputs.

Nonlinear damping control for interconnected nonlinear systems
2015 54th IEEE Conference on Decision and Control (CDC), 2015In this paper, we propose enhanced nonlinear damping control for a class of singularly perturbed interconnected nonlinear systems (SPINSs). The proposed method transforms SPINS into a feedback connection of two subsystems. Then, nonlinear damping is implemented to improve the transient behavior of slow subsystem.

Nonlinear observer design for Lipschitz nonlinear systems
Proceedings of the 2011 American Control Conference, 2011This paper presents a nonlinear observer design methodology for a class of Lipschitz nonlinear systems via convex optimization. A sufficient condition for the existence of an observer gain matrix to stabilize the estimation error dynamics is given in term of a quadratic stability margin.

Nonlinear Wave Interactions in Nonlinear Nonintegrable Systems
Studies in Applied Mathematics, 1998The main goal of this article is to understand the qualitative appearances of regular arrays of pulses that come up in nonintegrable systems in a variety of contexts, particularly in fluid dynamics. It is shown that even nonintegrable systems have a kind of particle dynamics made up of solitary waves.

Definition of eigenvalues for a nonlinear system
IFAC Proceedings Volumes, 2013In this paper the concept of eigenvalues and eigenvectors of nonlinear systems, both continuous- and discrete-time, is suggested. It represents a generalization of the concept known from linear control theory. Some basic properties, like invariance of eigenvalues under a (nonlinear) change of coordinates, possibility to transform the system to the ...

Factorization of Nonlinear Systems
1991We introduce a new concept of factor distribution for a nonlinear system as anew tool for studying the decomposition of such a system. The idea of factorizing generalizes a similar idea from linear system theory as well as the notion of controlled invariance for nonlinear systems.
