Control modernization of two-axis manipulator
Mejzlík, Jiří ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The bachelor thesis addresses the modernization of two-axis manipulator that is a part of the galvanizing line. The introductory section describes and evaluates the current situation and specifies the requirements for the device modernization. The selection of the proposed control is based on the analysis of possible solutions which are described in this work. The next part deals with the selection of suitable components and describes the process of implementation.

Control system for equipment using renewable energy sources
Novotný, Jan ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
The work deals with design of power and control electronics for water micro source in island network. In the general part the readers are acquaints with the issue of renewable energy sources and describes commercially produced micro sources. The practical part deals with the design of its own control system and power electronics using its own control system or PLC for water micro source. The microcontrollers were used for the implementation of the control system, for which the program part was created.

Laboratory device with temperature control
Telecký, Jakub ; Škrabánek, Pavel (referee) ; Němec, Zdeněk (advisor)
This work deals with regulation and procedures that can be used for this. The theoretical part therefore presents the basic concepts of automation and controllers. The main part is the practical part. The purchased system consists of a regulated system, which must be set up correctly. Using system identification and known procedures, sample examples of how to best set the controller are compiled. The result is a sample laboratory task that automation students can try and gain experience with methods of setting up the controller.

Leadership and management of personnel in construction company
Hegerová, Anežka ; Sláma, Lukáš (referee) ; Linkeschová, Dana (advisor)
This bachelor thesis deals with topics of leadership and staff management in the construction business. The purpose of the thesis is to analyze situation in the fields associated with problematics of Czech construction business. The theoretical part introduces concepts and theories related to said problematic. There are four hypotheses proposed in the practical part. The situation considering diversity, motivation, comunication and education is evaluated through survey. The outcome of this thesis are partial conclusions and suggestions derived from trends and experiences found through research. These conclusions and suggestions may be helpful for those holding leadership and employee management work positions in construction companies.

Audio D/A converter with external control using microcontroller
Špaček, Jan ; Stifter,, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This diploma thesis deals with the design of a laboratory measurement tool with ADC converter for audio and low frequency signals. In the introduction part a theoretical background of the ADC and DAC conversions are outlined. In the next chapters the technical solution of the laboratory converter is presented, including DAC with integrated circuit AD1852 and completed with digital audio receiver CS8416. This circuit secures compatibility with external audio devices with digital interfaces, like SPDIF or AES3. The digital receiver and audio DAC are added with serial communication interface for setup of the most audio and input parameters. This setup is operated by external microcontroller ATmega32 and original firmware. The thesis contains block diagram and schematic layout of the laboratory converter, including complete technical documentation for the construction and design.

HC08-Based Controller of a Step Motor
Hájek, Josef ; Růžička, Richard (referee) ; Strnadel, Josef (advisor)
This bachelor's work deals with issue of stepper motors and their control using single-chip microcontrollers. Target of the work is to be familiar with method of operation of stepper motors, with their abilities and restrictions in case there are used in built-in devices. The part of the work is a proposal of control unit of chosen stepper motor and interconnection with developmental kit 908LJ12-G2. Implementation part of the work contains software for eight-bit microcontroller Motorola MC68HC908LJ12 programmed in language C. The stepper motor can be controlled by this program using the available kit's interfaces.

Examples of governings with predictive controls
Šalda, Zbyněk ; Švarc, Ivan (referee) ; Němec, Zdeněk (advisor)
This thesis deals with model predictive control principally Based Predictive Control (MPC). The first part describes the principle of predictive control, cost function, the choice of a constraints in regulation and the choice of weights. In the next section is an analysis system: a system with non-minimal phase (control water turbine), oscillating systems (trolley frame control) and system with a time-delay . In all of these systems is performed classical feedback control using PID control and concurrently regulation with the MPC. MPC is selected as the solution fy Mathworks Model Predictive Control Toolbox and Simulink. The results are then analyzed using the criteria of quality control.
