A chaotic secure communication scheme based on duffing oscillators and frequency estimation
Zapateiro, Mauricio; Vidal Seguí, Yolanda; Acho Zuppa, Leonardo (2013)
Conference report
Open AccessThis work presents a new technique to securely transmit and retrieve a message signal via chaotic systems. In our system, a two-valued message signal modulates the frequency of a Duffing oscillator sinusoidal term. An ... -

A fault detection method for pitch actuators faults in wind turbines
Tutivén Gálvez, Christian; Vidal Seguí, Yolanda; Acho Zuppa, Leonardo; Rodellar Benedé, José (2015)
Conference report
Open AccessThe paper presents a model-based fault detection method for pitch actuators faults using the normalized gradient method to estimate the parameters of the pitch actuator. One major difficulty is that the input signal to the ... -
A long-short-term-memory neural network approach to early fault detection of wind turbines' main bearing based only on SCADA data.

A modified Chua chaotic oscillator and its application to secure communications
Zapateiro, Mauricio; Acho Zuppa, Leonardo; Vidal Seguí, Yolanda (2014)
Article
Open AccessIn this paper, a new modified Chua oscillator is introduced. The original Chua oscillator is well known for its simple implementation and mathemati- cal modeling. A modification of the oscillator is proposed in order to ... -
A secure communication design based on the chaotic logistic map: an experimental realization using Arduino microcontrollers

A secure communication system based on a modified chaotic chua oscillator
Zapateiro, Mauricio; Acho Zuppa, Leonardo; Vidal Seguí, Yolanda (2014)
Conference lecture
Open AccessIn this paper we propose a new scheme for secure communications us- ing a modified Chua oscillator. A modification of the oscillator is proposed in order to facilitate the decryption. The communication system requires two ... -
A velocity based active vibration control of hysteretic systems
Pujol Vázquez, Gisela; Acho Zuppa, Leonardo; Pozo Montero, Francesc; Rodriguez, Arturo; Vidal Seguí, Yolanda (2011-01)
Article
Open AccessHysteresis is a property of systems that do not instantly follow the forces applied to them, but react slowly, or do not return completely to their original state. A velocity based active vibration control, along with a ... -
A velocity based active vibration control of hysteretic systems

Acceleration-based fault-tolerant control design of offshore fixed wind turbines
Tutivén Gálvez, Christian; Vidal Seguí, Yolanda; Rodellar Benedé, José; Acho Zuppa, Leonardo (2016)
Article
Open AccessWind turbines (WTs) are basically controlled by varying the generator load torque (with the so-called torque control) and the blade pitch angles (with the so-called pitch control) based on measurement of the generator shaft ... -
Active control of hysteretic base-isolated structures via delayed signals
