Knowledge
The student who successfully completes the course will reach a solid knowledge of basic issues of modeling, dynamics and control of industrial processes; will know about measurements of base process variables, valve characteristics and controller algorithms; will be aware of criteria for stability studies and controller design and tuning; will be able to select the more appropriate control structure to achieve desired control performance. In addition will be able to use software for simulation of responses, to write simple computer codes for controller design and evaluation of controller performance.
Assessment criteria of knowledge
During the oral exam the student must be able to demonstrate acquired knowledge of the course material and to discuss the assigned project to explain adopted assumptions, choices and design techniques.
Methods:
- Final oral exam
- Written report
Further information:
The final oral exam, consisting in the discussion of a written report regarding an assigned project and in discussion of subjects included in the program, constitutes the global (100%)evaluation.

Syllabus
The course introduces to basic aspects of process dynamics: modeling of simple processes in the time, Laplace and frequency domain, responses to different inputs. Characteristics on instrumentation, valves and controllers met in industrial applications; open loop and closed loop behavior; feedback control. Definition of stability, criteria and techniques to evaluate stability conditions. Performance assessment; design criteria to achieve desired performance specifications; tuning rules of PID controllers. Control structure to improve disturbance rejection; feed-forward, cascade, selective and priority control. Illustration of logic and characteristics of control schemes applied in industrial plants. Use of software to perform control design and simulation of system response to different inputs.
