Some Results in Stability Analysis of Hybrid Dynamical Systems
(2011)
In this paper we introduced a general model for the Hybrid Dynamical Systems and for such systems we introduced the usual concept of Lyapunov stability. Furthermore, we established two Principal Lyapunov Theorems and a ...
CONTROL OF UNCERTAIN DYNAMIC-SYSTEMS USING STRICTLY POSITIVE REAL SYSTEMS
(Springer, 1990-01-01)
This paper presents necessary and sufficient conditions to turn a linear time-invariant system with p outputs, m inputs, p greater-than-or-equal-to m and using only inputs and outputs measurements into a Strictly Positive ...
Robust Control with Dynamic Compensation for Human-Wheelchair System
(Springer, 2014-12)
This work presents the kinematic and dynamic modeling of a human-wheelchair system, and dynamic control to solve the path following problem. First it is proposed a dynamic modeling of the human-wheelchair system where it ...
Dynamical characterization of fully nonlinear, nonsmooth, stall fluttering airfoil systems
(2022-02-01)
Stall flutter is turning into a more likely condition to be encountered as the demand for increasingly more flexible wings grows for HALE-like aircraft. Due to the various nonlinearities involved that can lead to complex ...
A mechanical analogous model for the power system with Automatic Voltage Regulator
(2010-02-01)
This paper deals with the subject-matter of teaching immaterial issues like power system dynamics where the phenomena and events are not sense-perceptible. The dynamics of the power system are recognized as analogous to ...
Global dynamics in galactic triaxial systems, I
(EDP Sciences, 2006-08)
We present a theoretical analysis of the global dynamics in a triaxial galactic system using a 3D integrable Hamiltonian as a simple representation. We include a thorough discussion on the effect of adding a generic ...
Underlying structure of the system using dynamic clustering and penrose inverse
(International journal of mathematical models and methods in applied sciences. Issue 4, Volume 2, 2008, 2009)
Dynamics and control design via LQR and SDRE methods for a maglev system
(2015-01-01)
Several experimental maglev systems all around the world, mainly in Germany and Japan have demonstrated that this mode of transportation can profitably compete with air travel. However, a system such as the German maglev ...
Brand equity evolution: a system dynamics model
(Associação Nacional de Pós-Graduação e Pesquisa em Administração, 2009)
One of the greatest challenges in brand management lies in monitoring brand equity over time. This paper aims to present a simulation model able to represent this evolution. The model was drawn on brand equity concepts ...
A complex biological system: the fly´s visual module
(Royal SocietyLondon, 2008-02)
Is the characterization of biological systems as complex systems in the mathematical sense a fruitful assertion? In this paper we argue in the affirmative, although obviously we do not attempt to confront all the issues ...
