Creating communication between Power Panel
Motl, Jakub ; Malounek, Petr (referee) ; Chomát, Luděk (advisor)
Theoretic part of my bachelor's thesis deal with possibilities in communication between Power Panels, made by B&R company. Describes possible communication between more PLCs, visual facilities and list of B&R company products. Furthermore some technical literature, RS232 interface, Ethernet, Ethernet PowerLink, CAN, PVI manager. The Practical part describes how to make a communication using INA 2000 protocol dedicated RS232 interface, Ethernet net with star topology. Furthermore program solution with regard to snake game visualization draft.

Servomotor with electronic commutating and his control and adjusting.
Schmied, Miloš ; Chomát, Luděk (referee) ; Pivoňka, Petr (advisor)
This thesis deals with the analysis of the actuator ACOPOS and its accessories. There are described the cascaded control loop concept and the setting servomechanism from B&R Automation with the important parameters. We follow the draft a speed controller servomotor with a load with the regards to knowledge of the control system. We compare the different methods of labor control actuator at last. There are implemented laboratory tasks of Position servomechanism and speed servo controller-on-load as a demonstration of our achieved results.

Industrial PID controller with autotuning and visualisation
Prudký, Miroslav ; Chomát, Luděk (referee) ; Pivoňka, Petr (advisor)
The objective of the thesis is to create software, which implements industrial PID controller enabling smooth switch-over and automatic tuning of parameters. The next objective is to create visualization for this controller. Whole controller have to be implemented into PLC Power Panel (B&R company). At the beginning of the thesis there is theoretical description of all implemented algorithms (discrete control algorithms derived from PID, smooth switch-over, antiwindup, identification algorithms). In the following there is designed program structure, which is state machine-shaped. All algorithms are implemented in ANSI C at first as s-function for Matlab/Simulink program, which enables to simulate and verify the controller. Implementation of controller into PLC Power Panel through the use of Automation Studio program from B&R company is described in the next part. Visualization is created in the same program. Simulations and verifications on mathematical and physical model demonstrates functionality of implemented algorithms, but also points out some problems associated with the use of identification algorithms in real world (noise, quantization in A/D and D/A converter).

Temperature controller of microwave reactor
Pokorný, Ondřej ; Chomát, Luděk (referee) ; Pivoňka, Petr (advisor)
Simple low-cost temperature feedback control loop was created, using personal computer as control and data acquisition element. It controlled the temperature inside mircowave pressure reactor. Medium in reactor tank (volume about 600 ml) was calorified by 1,8 kW magnetron, which power was driven by PSD controller. The PC- process interface was made by USB data acquisition modul UD128A8D. The utility program was written. It implemented PSD controller and data acquisition function. Furhtermore it implemented interface which enabled user to set the technological curve (time-temperature relation). The protocol of experiment was automatically stored to Micosoft Excel file before the program’s termination.
