Automated stand for laboratory work on the study of on-off controller

The basic information about automatic control, in particular the model laws of regulation, is studied by students of almost every technical direction of secondary special and higher education.. As part of the study of the theory of automatic regulation, the laboratory installation that includes a bruder model, a on-off controller OWEN TRM-202, a personal computer with installed software and an AC-3 interface adapter has been used. During the laboratory work, the controller is configured and data is recorded on the change of the controlled value over time in various operating modes and/or with different parameters of the elements, which allows to clearly demonstrate the features of two-position regulation and modern industrial automation technologies. Also, with the help of the Russian software package SimInTech structural modeling of two-position regulators is performed based on experimentally determined transfer functions of elements. Thus, the laboratory setup allows not only to demonstrate the operation of two-position regulators and adjust them to the specified quality indicators, but also to study the properties of regulators in modes that are not available on the physical model.
