Hello everybody,
So much happiness to share with you by part of our work developed.

There are here some articles which were presented in some Engineering Congress around the world. There is so much gladness to understand science as a wonderful language to explain and to look for solutions of different problems to protect the nature and to keep the balance necessities in society...

Thank you for your time to visit our group.

Best Regards,
AC.


There are here the abstracts:
1. Analysis and Implementation of Active Noise Control Strategies using Piezo Actuators
Ventilation systems are used in order to provide an appropri-
ate temperature inside buildings. For this reason, convection
heat transfer is achieved by fans and extractors to produce
wind flows. Nevertheless, fans are loud in operation, there-
fore passive or active mechanisms are used to reduce the
noise level inside buildings. However, passive mechanisms
are costly and need big space to be fixed around the ven-
tilation system to absorb noise compared to Active Noise
Control (ANC).
ANC systems are being employed to avoid big costs and
space requirements. Accordingly, strategies and algorithms
for active noise reduction were analyzed, implemented and
tested experimentally in this paper for applications in duct
ventilation systems. Algorithms implemented were simu-
lated by Matlab software. Piezo actuator was utilized as an
active element of ANC system during experimental testings.
2. Analysis of Online Active Noise Control Strategies by Hybrid Algorithm
Engines operations usually produce intense noise and
may cause hearing injuries. Therefore, passive absorbers are
being used to reduce or eliminate unwanted noise. However,
this mechanism is connected with high costs and space re-
quirements. Active Noise Control (ANC) allows to eliminate
mentioned drawbacks and therefore offers a better solution.
ANC can be designed by feedback, feedforward or hy-
brid algorithm. Hybrid algorithm has an average settling
time, but allows a good response in presence of disturbances.
In this paper a fair noise reduction is shown for the use case
where an identification process is being made inside of the
main hybrid control algorithm loop (online).
3. Control Strategies for a Prototype of Active Magnetic Bearing System
Electrical energy in Peru is usually produced by mechani-
cal energy conversion from strong ?ow rivers and ?ow winds.
Nevertheless, when rotor works at maximum power it loses
energy by heating, because of contact with bearings [ 7.2]
also heat evacuated a?ects thermal environmental conditions
(local population, animals, and plants). On the other hand,
a wrong positioning of rotor causes its unbalance. For this
reason in this work, is proposed some control strategies to
achieve a position and speed controller by active mechanism:
Active Magnetic Bearing (AMB). Furthermore, an environ-
mental protection is warranted owing to no friction presence
between rotor and bearing.
