Model reference pi controller tuning for second order inverse response and dead time processesand science
(2016-09-06)
In this paper, a One-Degree-of-Freedom PI controller is optimized using the model reference tuning approach for a Second Order Inverse Response and Dead Time Process operating as a servo control. In addition, a graphic ...
Development of a Mobile Application for Robust Tuning of One- and Two-Degree-of-Freedom PI and PID Controllers
(2015-12-01)
This paper presents the development of a mobile application for Android systems devices, that helps in the control system design task. The application allows to compute the parameters of PID-type controllers. The controlled ...
Improved PID controller tuning rules for performance degradation/robustness increase trade-off
(2016-09)
Definitely, robustness is an important feature that any control system must take into account, especially considering that the design is usually based on low-order linear models that represent the whole controlled process. ...
Monitoring the moin beach to control morphological changes due the construction of the moin container terminal, Limon
(2016-05-10)
The Moin Container Terminal (MCT) is a project under construction that represents one of the largest investments in
Latin American port facilities. The first stage consists of a seven million cubic meter sand fill constructed ...
Using the oxyhydrogen as an additive to increase the performance of an internal combustion engine
(2016-06)
Reducing the pollution emission associated with oil combustion is gaining an increasing interest
worldwide. Recently, Brown’s gas (HHO gas) has been introduced as an alternative clean source of energy. A
system to generate ...

Considerando que Costa Rica estará sumamente expuesta
a la amenaza de un clima cambiante, la respuesta
al cambio climático no puede esperar. Ya la mayor variabilidad
climática y el fenómeno El Niño-Oscilación del Sur ...
S809 Airfoil: Reynolds number effect on the aerodynamics of wind turbine blades
(2015-12)
The objective of this work is to study the S809 airfoil profile used in the wind turbine blades of horizontal axis. Wind turbines developed rapidly in technological terms, showing reliability in generating energy from the ...
Use of drone technology and photogrammetry for beach morphodynamics and breakwater monitoring
(2016-05-10)
Results from the use of UAV-based photogrammetry for monitoring changes in beaches and breakwaters are presented. Main recommendations are provided on the basis of lessons learned about the collection of reliable results ...
