Chaos control of a nonlinear oscillator with shape memory alloy using an optimal linear control: Part I: Ideal energy source
(Nonlinear Dynamics, 2009-01-01) [Artigo]
In this paper, an optimal linear control is applied to control a chaotic oscillator with shape memory alloy (SMA). Asymptotic stability of the closed-loop nonlinear system is guaranteed by means of a Lyapunov function, ...
Analytical study of the nonlinear behavior of a shape memory oscillator: Part I-primary resonance and free response at low temperatures
(Nonlinear Dynamics, 2010-03-01) [Artigo]
In this work, the response of a single-degree-of-freedom shape memory oscillator subjected to the excitation harmonic has been investigated. Equation of motion is formulated assuming a polynomial constitutive model to ...
On a nonlinear and chaotic non-ideal vibrating system with shape memory alloy (SMA)
(Journal of Theoretical and Applied Mechanics, 2008-01-01) [Artigo]
In this paper, we present nonlinear dynamic behaviour of a system which consists of a mass connected to a rigid support by a shape memory alloy (SMA) element and a damper. In order to disturb the system, a DC motor with ...
Analytical study of the nonlinear behavior of a shape memory oscillator: Part II-resonance secondary
(Nonlinear Dynamics, 2010-06-01) [Artigo]
In Part II of this work, we investigated the dynamics of the shape memory oscillator, in the particular case of the secondary resonances. We used the equation of motion developed in Part I (Piccirillo et al., Nonlinear ...
Chaos control of a nonlinear oscillator with shape memory alloy using an optimal linear control: Part II: Nonideal energy source
(Nonlinear Dynamics, 2009-05-01) [Artigo]
In Part II of this two-part work, we apply an optimal linear control technique to suppress chaotic behavior in a SMA oscillator, driven by a DC motor with limited power supply (Nonideal sources). Nonideal sources of ...
