Program

I: Theory and Practice in Process Dynamics. Introduction: system and model concepts; steady-state and dynamic models; variables and degrees of freedom; input and output variables. Dynamic Behaviour of Processes: time and Laplace Domain; transfer function; deviation variables; standard process inputs; linearization. Dynamic Behaviour of Standard Processes: first order system; capacitance; second-order systems; non- interactive and interactive system series. Dynamic Behaviour of More Complex Systems: poles and zeros and their effect; time delay; plug-flow reactor; difusional reactor; system series. Frequency Response Analysis: sinusoidal input; frequency response theorem; Bode diagram.
II: Theory and Practice in Process Control: Overview of control system design; dynamic behaviour and stability of closed-loop control systems; PID controller design, tuning and troubleshooting; control system design based on frequency response analysis; feedforward and ratio control; enhanced single-loop control strategies (cascade control); design of digital controllers; P&I diagrams.
III: Industrial instrumentation: Instrumentation for process control; basic principals of industrial measures; industrial sensors and transmitters; final control elements; distributed digital control systems; communications.

Eligibility for exams

Fequency of the lectures following the legal rules.

Calculation formula of final grade

Evaluation is in a scale of 0-20.
Final individual written exam (FIWE), lasting a maximum of 3 hours with 3 parts:
Part 1: Theoretical part, closed book and no calculator usage;
Part 2: Problem solving part, open book (one document) and calculator usage;
Part 3: Problem solving part, open book (one document) executed with the aid of a computer.
FINAL MARK = 0,35*P1+0,35*P2+0,3*P3
