Optimal operating points of oscillators using nonlinear resonators
Luis Guillermo Villanueva Torrijo
We demonstrate an analytical method for calculating the phase sensitivity of a class of oscillators whose phase does not affect the time evolution of the other dynamic variables. We show that such oscillators possess the possibility for complete phase nois ...
2012Passive damping of composite blades using embedded piezoelectric modules or shape memory alloy wires: a comparative study
Véronique Michaud, Antoine Sigg, Andrea Bergamini
Emission reduction from civil aviation has been intensively addressed in the scientific community in recent years. The combined use of novel aircraft engine architectures such as open rotor engines and lightweight materials offer the potential for fuel sav ...
Institute of Physics2012Design of Shunt Electric Networks in View of Sound Absorption with Loudspeakers
Hervé Lissek, Romain Boulandet
Variable acoustic properties can be obtained at the diaphragm of a loudspeaker, with the help of very basic control strategies, among which is the simple electrical shunting of the transducer. These shunt techniques have been demonstrated to present singul ...
2011Electroacoustic absorbers II: implementation of a digital synthetic admittance for controlling the dynamics of electroacoustic absorbers
Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet
This paper discusses the implementation of a synthetic electrical admittance for controlling the dynamics of electroacoustic absorbers. Indeed, different basic control techniques are capable of varying the acoustic impedance of an electroacoustic transduce ...
