Industrial PID controller with autotuning and visualisation
Vávra, Pavel ; Dvořáček, Martin (referee) ; Pivoňka, Petr (advisor)
This thesis deals with implementation of industrial used controlling block into Power Panel equipment of B&R in integrated development environment Automation Studio 3.0.71. It is PID controller with autotuner and visualization, which allowed bumpless transfer among controlling algorithms and manual control. PID and I-PD controllers with filtering of derivative action and dynamic antiwindup were implemented. Parameters of PID controller is possible to tune with the aid of ultimate gain and ultimate period according rules of Ziegler-Nichols. Ultimate parameters of controlled plant is possible to acquire with the aid of two identification methods, recursive least squares method and relay feedback. Recursive least squares method was implemented with directional forgetting. For relay feedback were used two types of relays: ideal and saturation relay for improving accuracy of searched ultimate values. The whole solution is programmed in ANSI C which Automation Studio supports. Created controller is control with the aid of touchscreen which is integrated in Power Panel. Trends of process values are viewed on the screen too. For comparison adaptive controller by B&R was implemented. This contoller is standardly supplied with Automation Studio in LoopConR library. All created algorithms were first validated on mathematical model of plant and then on real model in laboratory. The first part of thesis deals with theoretic analysis of used methods. The practical realization is described in the second part of this diploma thesis.

ABB RobotStudio - robot control using PLC B&R Automation
Mittaš, Eduard ; Lacko, Branislav (referee) ; Lang, Stanislav (advisor)
The goal of this bachelor thesis is to demonstrate various ways of communication with the controller of the robot as well as consecutive controlling of this robot. The simulation will be achieved by using the TCP/IP protocol, while the communication in the laboratory with real equipment will be assured by Profinet bus. This thesis will show also another solution, which is simple communication and connection between Microsoft Visual Studio and Robotstudio by using TCP/IP protocol. Initial chapters will describe ABB and B&R Automation companies, their control systems, history and information associated with them. Following chapters will serve as a guide describing creating of application in each of three presented solutions.

Meassuring system for building constructions
Flagar, Vojtěch ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
This paper deals with the hardware and software design of the data acquisition distributed system with large amount of connected sensors. The intended application of this work is measuring some physical quantities in the building constructions. The designed system is hierarchically divided into the three levels. On the highest level there is a single-board computer Raspberry Pi which is used as a master on RS-485 bus. There can be up to 32 slave devices on the bus while each of them collects data from the sensors connected to 4-channel I2C bus. At the same time the Raspberry Pi is used as a web server, providing the user interface of the system.

Small programmable bench power supply
Čech, Jonáš ; Vochyán, Josef (referee) ; Kubíček, Michal (advisor)
This bachelor‘s thesis deals with design and construction of compact low power switching power supply, which is powered from USB. It provides adjustable output voltage in range from 0 V to 16 V and adjustable current limit. The design is made with respect to galvanic insulation between device and PC. The control of device is done by basic user interface and software, which provide monitoring of output voltage, current and output power. The simulation and measurement results are included.

Noise meter and sound detector
Jedlička, Petr ; Novák, Marek (referee) ; Povalač, Aleš (advisor)
This work deals with design and construction of a noise meter, which measures sound pressure level. The device can be set either for weighting filter A or for weighting filter C considering the characteristics of human hearing, the device also allows two modes, fast and slow, depending on the rate of changes of sound pressure level. It tis possible to send measured data to a PC through a measuring application. The noise meter can be powered either by three AA batteries or by a PC through USB interface. The noise meter can be controlled by voice commands.
