Laboratory task arm pitch control by propeller thrust
Hindrich, Tomáš ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
This master thesis deals with the development and design of pendulum arm where the controlled variable is pitch of the arm. The goal is to stabilize the position of the arm in a horizontal position. Its position is controlled by changing the thrust of the propeller. Three types of controllers, PID, fuzzy PID and LQI controller are used to control the speed of the BLDC motor, which creates thrust together with the propeller. All controllers are designed and tested in Matlab/Simulink software, where the mathematical model of the system is controlled by them, then firmware for STM32F446RE containing controllers programmed in C language is created. For controlling the real system by user, the UI is created in C# .Net Framework. All controllers are then tested and tuned in order to be able to run on a real system and compared with each other. The model will then be used to test different types of controllers in teaching.

Inverted pendulum realization based on Cubli
Ježek, Michal ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
This master thesis deals with the development and construction of the inverted pendulum, inspired by the Cubli project. The objective is to develop and design an inverted pendulum, in the shape of one side of the cube balancing at one of its corner and for balancing is used the flywheel. For its design 3D printing is used to the maximum extent and as the electronic parts commonly available components at an affordable price are used. The design of the construction and the components allow the construction of a complete cube, without the need of further development or fundamental changes in the design of the model. For the calculations and the design of the controller the Matlab / Simulink software was used. As the controller algorithm the LQR algorithm is used with added integral feedback, to minimize control error. The 3D models of the single parts are created with FreeCAD software and printed on a 3D Prusa i3 MK2S printer.
