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 L2-GAIN SUBOPTIMAL CONTROL

Automatica, 1995
The chain-scattering formalism transforms the control problem into an easier factorization problem. In the paper, the formalism is extended to the nonlinear case, especially in the small signal case. Under some specific conditions, sufficient conditions for the existence of a suboptimal controller in terms of a state-space description of the plant as ...

Adaptive nonlinear control with nonlinear swapping

Proceedings of 32nd IEEE Conference on Decision and Control, 2002
We present a new approach to adaptive nonlinear control based on a complete controller-identifier separation which has long been a goal in adaptive system design. In this approach it is possible not only to separately design and analyze the parameter identifier, but also to independently guarantee properties achieved by the controller.

Finite-time command filtered backstepping control for a class of nonlinear systems

at - Automatisierungstechnik, 2018
This paper considers the problem of finite-time tracking control for a class of nonlinear systems. A novel finite-time command filtered backstepping approach is proposed by using the new virtual control signals and the modified error compensation signals.

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.

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 inferential control

AIChE Journal, 1988
AbstractNonlinear inferential control (NLIC) has been developed as a method for improving control of nonlinear systems. The controller is modelbased, and allows for direct use of available measurements. This paper presents the structure of NLIC and the manner in which it is applied to processes when the controlled variables are measured. Also described

Resonant nonlinear control circuits

Electrical Engineering, 1938
The resonant type of nonlinear circuit containing a resistance, a condenser, and a saturable-core reactor is finding a number of applications in the various engineering fields,1 and an analytical treatment has here been developed to add to the understanding of the behavior of such circuits.

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
