This paper presents the modeling and control of an array of mini-heliostats developed for a solar central tower plant facility located outside of Hermosillo, Mexico. In order to deal with the real time implementation, an algorithm to significantly reduce the error that emerges in the solar tracking requirements is presented. Heliostats are oriented...

... have developed a nine mini-heliostats test bench plant in Hermosillo, Sonora as part of a solar heliostat field facility, the so-called "Campo de Prueba de Heliostatos (CPH)", the test bench consists of a matrix array of nine 1.5 m 2 mirrors as shown in Figure 5. Even though the nine mini-heliostats plant can be controlled individually, we use one heliostat to illustrate our approach. ...

Given the collector acceptance angle = AE17.5 milli-rad [12], it is possible to establish the bound of the deviation angle < =jrj.

Project Oriented Learning in Mechatronics courses curricula is a key aspect in the teaching-learning process. In addition,
graduated engineers with competences in design and implementation of renewable energy systems are in strong demand by
today’s society. This paper presents a solar tracking system test-bench used to track the path of the sun and to redirect the solar beams to a specific point. The system is composed by an electromechanical plant and a control system implemented in National Instruments LabVIEW IDE. Such system is proposed to carry out a project in mechatronics engineering curricula for introducing undergraduate engineering students to mechatronics design and prototype implementation in the context of actual renewable energies. This proposal aims to develop students’ competencies oriented to the design, implementation and validation of mechatronic systems. The experimental platform would allow the teacher to complement theoretical aspects, whereas students would learn in a challenging environment where they would generate a complex prototype focused to solve a current world problem.

This paper describes a multiagent architecture integrated system designed to supervise infrastructures in solar farms. The system enables monitoring the environment by means of sensor networks that are in charge of collecting data. It is designed using a hybrid model composed of an inference engine and an ontology. The former makes the system intelligent, while the latter structures knowledge. We have also developed a tool to configure and use the multiagent system in a simple and intuitive way.
