Process simulation and control

This course is part of the programme:
Master’s study programme Environment (2nd level)

Objectives and competences

The primary goal of this course is to teach students the basic principles of computer control and automation of engineering systems and processes.

Students obtain the following competences:

  • basic control principles and general methods of systems’ design and assembly,
  • knowledge of basic methods, tools and elements necessary for control-system design like: mathematical modelling and computer simulation, various methods for control design and implementation of control functions, computer-aided control-system design, and supervisory-control software.

Prerequisites

Required prerequisite knowledge of mathematics, physics, and computer science on a Bachelor’s level.

Content (Syllabus outline)

1. Introduction to system theory

  • Introduction to the course, to systems and system theory
  • Principles of control (open-loop, disturbance compensation, closed-loop)

2. Modelling and computer simulation of dynamic systems

  • Mathematical modelling, transfer function, modelling case studies
  • Case studies of modelling and computer simulation
  • Block diagrams
  • System identification with step response

3. Control-systems design

  • Systems presenation
  • Analysis of control systems in time domain
  • Basic industrial control algorithms
  • Continuous PID controller design
  • Examples of control systems
  • Multi-loop control systems

4. Higher control levels

  • Production level, process level
  • Process level, SCADA.

Intended learning outcomes

Knowledge and understanding:

Introduction to control system and general control principles are mastered first. The main part of the course is devoted to basic methods, tools and elements so that students are able to design simple control systems. In this framework students obtain basic knowledge of mathematical modelling and computer simulation, various control-design methods, implementation of control functions, computer-aided control-system design, and supervisory-control software.
