Distributed Control Systems

Prerequisite:

Control Systems (XE35RSY)

The course is a substitute for:

Distributed Control Systems (E35DRS)
Distributed Control Systems (X35DRS)

Lecturer:

Supervisor:

Department of Control Engineering

Synopsis:

The main aim is design and analysis of distributed systems for industrial

applications. Important part is oriented towards industrial communication

networks. Theoretical background and the system analysis are based on Petri

Nets specifically dealing with their structural properties, colored Petri

Nets, timed Petri Nets and other extensions. Several communication protocols

are modeled, simulated and analyzed. Parallel computers and parallel

languages are briefly mentioned in order to illustrate complexity evaluation

of parallel algorithms and global communications.

Requirements:

linear algebra, Matlab, PLC programming

Syllabus of lectures:

1. Distributed Control Systems, Enslow's model, Flynn's classification. Petri Nets modeling of distributed systems.

2. Petri Nets - Properties and Analysis of distributed systems

3. Classes, Abbreviations and Extensions of Petri Nets. Algorithm distribution by means of Petri Nets.
