Design of low-cost control unit for DC/BLDC motors
Pospíchal, Tomáš ; Najman, Jan (referee) ; Rajchl, Matej (advisor)
This thesis deals with design and construction of motor driver, firmware for STM32H7 a software UI in Python. Motor driver has four total half bridges, from two H-bridge Smart Gate Drivers. Motor driver is designed for 100W DC/BLDC motors. Communication over USB 2.0 HS, using CANOpen protocol with IEC 61800-7 device profile. Motor driver could be used for lectures and demonstrates USB 2.0 HS capabilities of STM microcontroller.

Design and manufacture of a two-wheeled unstable robot
Vecheta, Vít ; Dobossy, Barnabás (referee) ; Adámek, Roman (advisor)
The first part of this work contains a review of similar unstable robots, their drives, and control electronics. The practical part of this work focuses on the design and construction of a two-wheeled unstable robot. The first step involves conducting simulations to determine the necessary parameters of motors and other components. These simulations are used to establish the required specifications for the motors and other components. Subsequently, a mechanical design and electronics are developed. The practical section concludes with the proposal of a cascade PID controller for the robot’s control. The final part evaluates the robot’s balance capabilities, identifies design errors, and suggests possible future improvements.
