During my diploma thesis I created a device which is able to control the position of a ball in a tube with the control of a fan. The aim of this thesis was to make other students interested in control engineering. This device gives an opportunity to investigate the properties and the behavior of regulated systems as well as it is a spectacular demonstration of control processes.

The scope of my work was to adjust the former version of the hardware and to implement the embedded software responsible for the regulation. The system was designed in a way that multiple users can connect to it simultaneously, they can receive data from the device and make adjustments regarding its behavior.

I designed client-side applications for these purposes. The program on the microcontroller can be altered wireless, this way options can be changed without disassembling the device.

My work covered the investigations of approximation models as well, which can describe the levitation phenomenon. This creates opportunity to design and simulate control systems.
