Objective of the course is enabling the student to master the most common control methodologies and instrumentation equipments of the chemical and industrial processes, through the theoretical and experimental analysis of real control and measuring systems. The course aims at providing the student an overview of the fundamentals of system dynamics and feedback control theory, as well as of physical principles applied in measuring instruments; these are then applied to the analysis and operation of level, pressure, flow, temperature control loops. The theoretical and practical elements set the basis that will allow the student to address the analysis P&ID of single units and plants.

Modalità di valutazione
Organization of the course and exam
The course consists of regular lessons in the class plus lessons and practice in the Instrumentation Laboratory (in small groups, according to a schedule that is agreed at the beginning of the course). Students are requested to analyze the experiences in the labs, also through the development of mathematical models and produce reports that will be evaluated.
The final part on P&ID will involve flipped and blended classes.
The course includes seminars from experts in the field of instrumentation and visits to industrial sites.
The exam will be oral.
In the examination, the student will be asked general questions on the topics of the course, to verify the knowledge and comprehension of the fundamentals. The interview will also verify the ability of the student to use the general background matured to the quantitative analysis of specific cases. The student will discuss ona quantitative basis the lab experiences through the illustration and discussion of the reports.
