Radio Controled Tracked Vehicle Model
Ctibor, Jiří ; Knobloch, Jan (referee) ; Klíma, Bohumil (advisor)
The aim of the bachelor thesis is the design and creation of manufacturing documentation DC drive for the tracked vehicle model with remote control, its design, programing and inspirit. To create a manufacturing documentation it’s needed to be familiar with the design program for printed circuit boards Altium Designer. Program of the microprocessor will be created in CodeWarrior development environment in the C language. To design circuits were used generally datasheets of components. The proposal consists of several functional peripheral units that provide various functions needed. For control the circuit is used a digital signal processor aimed at applications in the motor drives.

Two-stroke Engine Pre-ignition Controller with Microcontroller
Veselý, Tomáš ; Vorel, Pavel (referee) ; Šebesta, Jiří (advisor)
This paper deals with the problem of two-stroke engine pre-ignition controller with the use of microcontroller for single-cylinder engine and double-cylinder engine. The mechanical design is drawn for motorcycles JAWA and ČZ and for engines of the same mechanical type. The establishment uses non-contact status analysis of engine with non-electric sensor. The very important thing for the design is the simplicity of the establishment. The other important thing is the minimisation of mechanical arrangement of engine and the vehicle as a whole. The importance of this establishment is non-contact switching and the possibility of changing pre-ignition maps depending on the number of rotations per minute, the temperature and the load of the engine.

Traction inverter for an electric bike
Prudík, Martin ; Klíma, Bohumil (referee) ; Vorel, Pavel (advisor)
A drive design for an electric bike with brushed DC disk motor is proposed in this thesis. Especially the design of a DC/DC converter with DSC control is described. The converter can operate as step-down and step-up too. Minimum dimensions and sufficient power for riding without human assistance were the main demands on the design.

Software for Laboratory stand with inverters and motors
Smolák, Martin ; Ctibor, Jiří (referee) ; Knobloch, Jan (advisor)
This bachelor‘s thesis focuses on control firmware for two microprocessors and visualization software of laboratory tasks on the computer. The first of the microprocessor controls a DC motor with permanent magnets and the second one an induction motor. The thesis first describes the hardware of the stand, the principle of AC motors control, Clark‘s and Park‘s transformation, description of firmware for DC and induction motor. Further there is described the visualization environment which serves students for controlling the stand and for calculation of the current regulator using the method of optimal module.

Heat pump control system
Kundrata, Radim ; Pech, Ondřej (referee) ; Hejčík, Jiří (advisor)
The rising costs of heating buildings are leading to the widespread use of energy-saving heat sources, including heat pumps. The purchase of a heat pump is a significant investment. A way to reduce the purchase costs is to build it yourself or to convert it from an old air-conditioning unit. One of the obstacles in converting these devices is their subsequent integration into the heating system of the house and their control. Therefore, the paper describes the design of a simple control system, which is primarily intended for these cases. It is based on the ESP32 microcontroller series. The control system has 13 configurable inputs for thermometers or digital inputs, 6 of which also allow analog input. It also has 9 outputs for relay connections. The control system can be connected wirelessly, its configuration is done via a web interface. The control system includes equithermal control, user adjustable thermostat, various methods for evaporator defrosting, bivalent source control, compressor protection elements, refrigerant overheating measurement. All setting options are described in the text of the thesis. The source code for the microcontroller and the web configuration page are included in the appendix of the thesis.
