摘要：AbstractPID controllers are the most frequently used controllers. Theoretical understanding of the system to be controlled and the working principle of PID controllers are crucial for closed-loop control. This fundamental knowledge is - in principle - learned by all engineering students at the undergraduate level. However, understanding the practical aspects of the application of a PID controller and their connections to theoretical concepts must be combined in a clever way. This paper explores the process of the development of a low-cost, easy to manufacture demonstration setup which can act as the bridge between the theoretical and practical world of the control system knowledge. As a reaction to the COVID epidemy, this project is made with the philosophy that the students should be able to take these setups home or even replicate them themselves. The proposed setup comes with an interactive block diagram-based graphical user interface which allows the user to observe the physical changes of the process in -nearly- real-time. The aim of the provided exercises is to comprehend the similarities and the difference between the theoretical and practical aspects of closed-loop control. This paper explains the components of the setup, the development process, the recommended exercises, and feedback from our students.
