Aeroelastic analysis and characterization of three-degree-of-freedom systems with discontinuous nonlinearity
(2020-01-01)
The effects of freeplay, multi-segmented, and impact nonlinearities in the pitch and control surface degree of freedoms on the behavior of a three-degree of freedom aeroelastic system are investigated. The aeroelastic ...
On non-linear and non-ideal interactions in two vibrating problems
(2008-06-17)
In practical situations, the dynamics of the forcing function on a vibrating system cannot be considered as given a priori, and it must be taken as a consequence of the dynamics of the whole system. In other words, the ...
On relaxed LMI-based designs for fuzzy regulators and fuzzy observers
(2001-01-01)
Relaxed conditions for the stability study of nonlinear, continuous systems given by fuzzy models are presented. A theoretical analysis shows that the proposed method provides better or at least the same results of the ...
The fractional-nonlinear robotic manipulator: Modeling and dynamic simulations
(2012-12-01)
In this paper, we applied the Riemann-Liouville approach and the fractional Euler-Lagrange equations in order to obtain the fractional-order nonlinear dynamics equations of a two link robotic manipulator. The aformentioned ...
On Robust Switched Controller Design to Minimize the Guaranteed Cost of Polynomial Fuzzy Systems
(2019-06-01)
This paper presents a robust switched controller design to minimize an upper bound of a quadratic index (guaranteed cost) based on the output and the control input of uncertain nonlinear systems described by polynomial ...
A new sufficient condition for optimal impulsive control problems
(2012-12-01)
In this article we introduce the concept of MP-pseudoinvexity for general nonlinear impulsive optimal control problems whose dynamics are specified by measure driven control equations. This is a general paradigm in that, ...
Nonlinear dynamics and control strategies: On a energy harvester vibrating system with a linear form to non-ideal motor torque
(E D P Sciences, 2012-01-01)
In this paper, we deal with the research of a vibrating model of an energy harvester device, including the nonlinearities in the model of the piezoelectric coupling and the non-ideal excitation. We show, using numerical ...
On optimal control of a nonlinear robotic mechanism using the saturation phenomenon
(2015-01-01)
In this paper a robotic arm is modelled by a double pendulum excited in its base by a DC motor of limited power via crank mechanism and elastic connector. In the mathematical model, a chaotic motion was identified for a ...
Bifurcation Analysis of a Piecewise-Smooth Freeplay System
(2022-01-01)
Physical systems that are subject to intermittent contact/impact are often studied using piecewise-smooth models. Freeplay is a common type of piecewise-smooth system and has been studied extensively for gear systems ...
