PI control of laboratory model elevator via ladder logic in PLC

Abstract

We summarize the design and implementation of a laboratory model "the Elevator" and its control. We focus on the hardware and software components and on the process of design, actual implementation and application control. The mentioned model is located at the Technical University in Kosice, Department of Cybernetics and Artificial Intelligence at the Center of Modern Control Techniques and Industrial Informatics. The model is used for education offering the possibility to implement various algorithms and programs in ladder diagrams.
