Theoretical contents will be presented in lectures, always with the active participation of the students and support of audiovisual tools. The seminars will be dedicated to solving problems in some cases with the help of computer tools. At the end of the different sections of the discipline, evaluated seminars will be held. The students will solve theoretical questions or problems. The obtained grades will be included in the final evaluation.
Interactive computer classroom seminars will focus on the dynamic analysis of chemical processes and controller tuning by means of Control Station's Loop-Pro software.
The two group tutorials will be used to study the feedback control of a heat exchanger (RYC-TAG Practice from Edibon)
Virtual Campus will be used as a support tool for teaching.
The student will also be able to attend to individual tutorials at the time established for this purpose.
