Iverter for three-phase motor
Mikuška, Martin ; Červinka, Dalibor (referee) ; Knobloch, Jan (advisor)
This master’s thesis goes into design of particular circuits for three phase inverter. Inverter’s control is ensured by digital signal controller MC56F8013 with his program. Principle of control is suggested for individual motors. Inverter design considerate universal use and capability for any three phase motor. Particular blocks are compatible each other.

Design of control board for BLDC motor
Zbranek, Petr ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
In the context of this master’s thesis are solved algorithms and hardware for control BLDC motor. The first was designed algorithm in LabView called "six-step". This algorithm causes a torque ripple, so in the final version was used vector control. It is a sensor control, so was necessary to design a measurement of rotor position. It was solved using a magnetic position sensor. After testing the control algorithm was designed my own hardware for control the BLDC motor. The main control unit was chosen microprocessor MC56F82743, which is designed specifically for BLDC motor control. The microprocessor was programmed in the CodeWarrior development environment, using a JTAF and USB-TAP.

Monitoring of environmental parameters in buldings
Slovák, Martin ; Číp, Ondřej (referee) ; Václavík, Vlastimil (advisor)
Aim of work is project system for monitoring environmental parameters in buildings. Theoretical part of work deals with parameters, which will be monitoring, why we measure those parameters in buildings. And what devices can we choose to do it. Measurement channel describes from change of physical value to electric value, after that there is a correction to processing by microcontroller. And those values are sending by microcontroller to other processing. The best solution to distant transmission is probably ZigBee technology. Practice part of work is in keeping with theoretical part. There are some practical sensor connections, where is difference in output of sensor. It’s necessary to project connections of sensor and do their software services. There is a simple tool to programming microcontrollers, which is called CodeWarrior. In last part is solution of algorithm, which make net by ZigBee technology.

Laboratory assignments for microcontroller ColdFire MCF52233
Dyčka, Ondřej ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
This master’s thesis contains design of practice exercises for microcontroller MCF52233 firm Freescale. Exercises are focused on working with basic peripheries as counters and timers, measurement with A/D converters, PWM modulation or I2C bus. Exercises are interested in evaluation of matrix keyboard and communication with alphanumeric display controller. To these exercises is made a preparation of external peripherals, which is connected with evaluation kit M52233DEMO. This preparation contains all necessary peripheries, which are used for practice exercises – buttons, LED diodes, potentiometer and I2C periphery. Individual periphery usually shares connection to microcontroller with another periphery. Therefore preparation contains switches, which are necessary to set up for correct functionality of the peripherals. The board of external peripheral also includes ports for connecting matrix keyboards and alphanumeric display. Connecting the display requires an external power supply. Work deals with implementation of laboratory exercises using a software firm Freescale. Development environment for programming and basic debugging is in program CodeWarrior. More advanced possibility of reading information from a running program in the microcontroller offers program FreeMaster, which is used in the exercise of AD converters. Each lab exercise contains an introduction, task, instructions and the flowchart of realized exercise. Instructions are written so that it contains important steps to properly manage assignments. Individual exercises are designed to gradually increasing complexity of exercises students obtain basic programming habits and manage the complex exercise.
