Control of Uncertain Nonlinear Systems

Journal of Dynamic Systems, Measurement, and Control, 1993
This paper describes some of my research in the analysis and control of nonlinear uncertain systems in which the uncertainties are modeled deterministically rather than stochastically. The main applications are to mechanical/aerospace systems, such as robots and spacecraft; the underlying theoretical approach is based on Lyapunov theory.

Invertibility of Nonlinear Control Systems

SIAM Journal on Control and Optimization, 1979
This paper gives necessary and sufficient conditions for the invertibility of nonlinear control systems of the form $\dot x = A(x) + uB(x)$; $y = c(x)$, where the state space is a real analytic manifold. For invertible systems we construct nonlinear inverse systems.

Perturbations of nonlinear controllable systems

1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes, 1980
In the class of nonlinear, nonautonomous control systems we consider the property of controllability to a compact set on a fixed time interval, and we give a sufficient condition for this property to be preserved under small perturbations of the control system.

Strong Controllability of Nonlinear Systems

SIAM Journal on Control and Optimization, 1986
Affine control systems defined by analytic vector fields are considered. The author individuates a subset of the Lie algebra associated to the system: the set of semicontrolled vector fields, which characterizes the strong controllability of the system. A method is given to determine some semicontrolled vector fields.

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 Integral System Control

2020 21th International Carpathian Control Conference (ICCC), 2020
This paper deals with the control of a nonlinear integral system in the form of a DC electric motor with worm gear and a microcontroller-based control unit. The aim is to control the angle of rotation of the output shaft. The paper tries to describe the nonlinearity of the system, which is caused by the typical characteristics of DC electric motors ...

Controllability of Perturbed Nonlinear Systems

IMA Journal of Mathematical Control and Information, 1989
Summary: Sufficient conditions for complete controllability of perturbed nonlinear systems with implicit derivative are given. The results are a generalization of the previous results of the author [IEE Proc., Part D 132, 14-17 (1985; Zbl 0554.93012)], \textit{G. Anchini, G. Conti} and \textit{P. Zecca} [Note Mat. 6, 99-111 (1986; Zbl 0612.93008)], and

Nonlinear System Control Strategies

Advanced Materials Research, 2013
A nonlinear model of a liquid level process is obtained on the analysis of its nonlinear characteristics. Then a practical nonlinear system control strategy of the liquid level process based on single chip computer is presented. By measuring the liquid level and flow rate, two key parameters of the liquid level process, the amplification coefficient ...
