DYNAMICS AND CONTROL OF ENERGY SYSTEMS
LEARNING OUTCOMES OF THE COURSE UNIT
The student will acquire
(i) basic knowledge for the study of the dynamic behavior of energy processes and machines and their control
(ii) tools for dynamic simulation of complex systems
(iii) modeling capabilities of components of systems of different nature, type and configuration. The student will be able to assess the complexity of the model and he will be able to make the appropriate simplification in order to obtain results of adequate accuracy also in relation to that of the available measures for calibration, validation and comparison.
(iv) ability to apply basic knowledge and learned methods for the study of more complex energy systems and more advanced control techniques.

ASSESSMENT METHODS AND CRITERIA
Oral exam consisting in the discussion of a group project and in some questions about the course content. The project is the development of a model of a fluid or thermodynamic system and its implementation in two computing environments to choose from Matlab, Scilab and OpenModelica.
