AUTOMATION FOR COMPLEX SYSTEMS | MIE090 |

**Aim**

The purpose of the course is to provide understanding for the problems that appear in large and complex industrial automation systems. Another purpose is to give fundamental knowledge about the tools and methods used for realisation, analysis and assessment of industrial automation systems. Many complex industrial systems today include a very large number of measurement points, controllers and actuators. A large process industry may include more than 200 000 measurement points. This requires large computer control systems and the handling of huge amounts of information. How can the information from such a large number of units be systematically condensed? The course describes and analyses how to structure this kind of complex systems. The primary goal of the course is to coordinate many unit processes or machines to properly conduct such an industrial orchestra.

*Knowledge and understanding*

For a passing grade the student must

- characterise industrial processes from a complexity perspective and understand how the complexity affects the application of automation;
- describe how to use mathematical models to solve typical automation problems;
- explain and use important concepts such as stability, real time demands, capacity, stationarity and dynamic stiffness.

*Skills and abilities*

For a passing grade the student must

- formulate and structure a mathematical model of an industrial process based on information about the constituting components and how they interact and by using this model analyse important characteristics of the process;
- structure a control system for a industrial process consisting of several process units;
- program a PLC to solve control tasks requiring several processes to run in parallel.

*Judgement and approach*

For a passing grade the student must

- assess the appropriateness of control, process monitoring and communication structures for industrial processes with complex relationships between key quantities.
