Objectives and competences
Presentation of control design transfer into practical implementation with the emphasis on computer control of technological processes, guidelines for hardware and software selection, introduction to computer implementation of control methods and algorithms, presentation of engineering software tools and their use in computer control implementation, presentation of subsystems integration into holistic automatic control system.
Teaching and learning methods
Lectures, laboratory exercises.
Expected study results
After successful completion of the course, students should be able to:
– select hardware and software for computer control system implementation,
– parameterize industrial closed-loop controls,
– program industrial logic controllers,
– design programmable control systems for technological processes,
