Adaptive controllers with principles of artificial intelligence and its comparison with classical identifications methods
Dokoupil, Jakub ; Malounek, Petr (referee) ; Pivoňka, Petr (advisor)
This piece of work deals with a philosophy of design adaptive controller, which is based on knowledge of mathematical model controlled plant. This master thesis is focused on closed-loop on-line parametric identification methods. An estimation of model´s parametres is solved by two main concepts: recursive leastsquare algorithms and neural estimators. In case of least-squares algorithm the strategy of preventing the typical problems are solved here. For instance numerical stability, accurecy and restricted forgetting. Back Propagation and Marquardt- Levenberg algorithm were choosen to represent artificial inteligence. There is still a little supermacy on the side of methods based on least-squares algorithm. To compare individual algorithms the grafical interface in MATLAB/Simulink was created.

Integration security systems to object
Sihelník, Jakub ; Chomát, Luděk (referee) ; Malounek, Petr (advisor)
The purpose of this thesis is the design and implementation of security system, fire system and closed-circuit TV. The first part describes the electrical safety technology, some methods for design and at the end is described several types of frequently used systems. Further are the reasons for needs of fire electric installation, design and installation to keep the principle of the primary use. The conclusion is described function of basic types of detectors and autonomous systems. Another part is devoted to closed-circuit television, basic types of cameras and recording devices. One chapter describes characteristics and properties of the integration software. In conclusion are described the reasons for selecting concrete systems, problems and observations recorded during the main installation and recovery, the necessary changes and alternatives.

Connection between PC and PLC through Ethernet Powerlink
Špaček, Marek ; Chomát, Luděk (referee) ; Malounek, Petr (advisor)
The aim of my bachelor‘s thesis is connection between PC and PLC with industrial network Ethernet Powerlink. This work describes the basic principle of Powerlink network connection and the option of connecting ordinary PC to Powerlink network according to Powerlink standard. This allows you to use your computer for setting parameters and visualization of other devices connected to the Powerlink network. The result of this work is an application that after the connection to the EPL network detects all active devices on the network, shows their names and eventually displays their variables.

Control system for the hardening furnace
Chovanec, Jozef ; Malounek, Petr (referee) ; Mikšánek, Vojtěch (advisor)
Subject of this work is to create control system for abyssal hardening furnace and project regulation of temperature. The function and construction of furnace is introduced. Next there are compared currently installed control system B&R 2005 and designed system B&R X20. Part of the work is economic analysis . Temperature in the furnace is controlled by algorithm, which should accurately follow given temperature curve in each of six section in process of heating workpiece.

Adaptive optimal controllers with principles of artificial intelligence
Samek, Martin ; Malounek, Petr (referee) ; Pivoňka, Petr (advisor)
Master’s thesis describes adaptive optimal controller design and it’s settings. Identification with principles of artificial intelligence and recursive least squares identification with exponential and directional forgetting are compared separately and as part of controller. Adaptive optimal controller is tested on physical model and compared with solidly adjusted PSD controller. Possibilities of implementation of adaptive optimal controller into programmable logic controller B&R are show and tested.

Technological process simulation
Dostál, Jiří ; Veselý, Libor (referee) ; Malounek, Petr (advisor)
This paper deals with a design of an inverted pendulum model and its controller in Matlab/Simulink, a conversion of the model and its controller to the ANSI C language and its implementation to B&R PLC's. The source code for B&R PLC's is generated automatically by the B&R Automation Studio Target for Simulink library. The first part deals with the design of a mathematical model of the inverted pendulum and its simulation in Matlab/Simulink, followed by a design of a LQ controller for this model using Matlab functions and a description of the B&R Automation Studio Target for Simulink library. The last part of this paper deals with the implementation of the model and its controller into two separate B&R PLC's, which are networked with the Ethernet Powerlink industrial fieldbus and it also describes visualizations that were designed for operating the system.

Heat technological process model
Krásenský, Jan ; Dokoupil, Jakub (referee) ; Malounek, Petr (advisor)
This work presents possibilities of X20AT2222 and X20AT2402 measuring cards. It describes design of physical heat tunnel with three sections, where each one has own heating elements. In detail is described technical solution and structure of model. Subsequently is designed controller and process visualization for PLC. Based on identified system and model structure is created system simulation in Matlab Simulink.
