Compact Trainer: Process Closed Loop Control

E6.3.3.1

Large, intricate processes are often broken down into sub-processes in the interest of clarity. This facilitates the step-by-step commissioning of production facilities and efficient error resolution when a breakdown occurs. The setup is comprised of various different sub-processes:

Each controlled system on its own is perfect for the execution of numerous experiments. At the same time the module experiment design featuring experiment plates allows for easy combination of sub-processes. If you integrate additional electronic transfer components (from E 6.3.4), then additional dead time and time constants arise that influence the entire process.

In this way technical processes, reproduced using experimentation plates, can be adapted to address any practical control engineering issue. Experiments with experiment plates are thus a cost-effective alternative to the large control models. Experiments with experiment plates all work with the Profi-CASSY interface. Together with the analysis and simulation software WinFACT, the measuring results can be immediately compared with a suitable computer simulation. This offers the opportunity to gather in-depth insight into the behaviour of relay processes.

The equipment set incorporates student experiments which can be carried out in a laboratory safely using safety extra-low voltage. Experiment instructions are contained in a manual in either printed or digital form.

The target group is made up of commercial apprentices and students of power engineering and mechatronics. The course offers introductory experiments at an intermediate level for vocational schools and colleges.
