Automatic Process Control

Home / Unidades Curriculares / Automatic Process Control

Base Knowledge

Basic knowledge of mathematics, physics and instrumentation.

Teaching Methodologies

Classes have two components: expositive and theoretical-practical. Throughout the semester it is provided support to students with the contents.

Learning Results

The main objective of this teaching unit is to promote, on who completes it successfully, the following competences

1. Simulation and control of processes in the food industry – this course follows the course on System Dynamics, and allows the analysis of the behavior of common controlled processes in food engineering.

2. Advanced mastery in food technology – this course, by providing a general understanding of the functioning of several common processes in the food industry, is important for an advanced mastery in food technology.

Program

1. Fundamental concepts of automatic control of processes: objectives and motivations; design of a control system; control configurations (feedback, anticipatory and inferential).

2. Feedback control: the controller and the basic control actions (proportional, integral and derivative); transfer functions of controllers; direct and inverse controller action.

3. Control loop elements: measuring instruments; transmitter; transmission lines; final control elements; block diagram representation of controlled process.

4. Dynamic response of closed loop control systems: servo and regulator problem; resetting deviation.

5. Stability analysis of feedback control systems: general stability criterion, Routh stability criterion, direct substitution method.

6. Design of feedback controllers. Static and dynamic performance criteria.
