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.

Computational Nonlinear Control.

1992
Abstract : The goals of this research project were the development of control and estimation algorithms for nonlinear systems which are computationally feasible with robust performance despite numerical and modeling errors. The approach was based on the recent generalization of linear worst case (H-infinity) controllers to nonlinear systems.

Controllability of Nonlinear Sequential Networks

Journal of the ACM, 1970
A sequential network is said to be controllable if there exists at least one integer k such that it is possible to transition between any pair of arbitrary states ( S α , S β ) in exactly k steps. In this paper, necessary

Global Controllability of Nonlinear Systems

SIAM Journal on Control, 1972
This article deals with the controllability of nonlinear differential systems which arise when a linear system is perturbed. The sufficiency conditions presented insure that the nonlinear system will be (globally) controllable whenever its linear part is controllable. Moreover, the steering can be accomplished using continuous controls with arbitrarily

Nonlinear learning control for a class of nonlinear systems

Automatica, 2001
A 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.

Nonlinear Metabolic Control Analysis

Metabolic Engineering, 1999
Mathematical description of metabolic systems allows the calculation of the expected responses of metabolism to genetic modifications and the identification of the most promising targets for metabolic engineering. Metabolic control analysis (MCA) provides such a description in the form of quantitative indices (elasticities and control coefficients ...

Nonlinear damping control for interconnected nonlinear systems

2015 54th IEEE Conference on Decision and Control (CDC), 2015
In 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 controllers for nonlinear passive systems with arbitrary input nonlinearities

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
A nonlinear dynamic compensator framework for nonlinear passive systems with arbitrary input nonlinearities is proposed. For this class of systems we prove global closed-loop stability by modifying the dynamic compensator to include a suitable input nonlinearity.
