Sinumerik tools for synchronous programming of CNC machines
 Toman, Martin ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This thesis deals with advanced programming of CNC milling machines in Sinumerik 840D powerline control system. Mostly it is aimed on issues of synchronized actions. These actions can adaptively react on progress of milling process regarding to signal detection from the machine and execute specific action. In the introduction of the thesis there are briefly described basic issues and fundamentals of CNC machines and control systems programming. The problematic regarding the programming of synchronized actions is also described. The examples with evaluation of their function are created in the practical part of thesis.

Adaptive controllers with principles of artificial intelligence
 Pitra, Michal ; Malounek, Petr (referee) ; Pivoňka, Petr (advisor)
The diploma thesis is focused on an adaptive control, especially in a self-tuning controller area. The thesis is divided into two main parts. The first part deals with identification methods of the adaptive control. The recursive least squares algorithm and the neural network method are the most popular identification methods. These methods are contrasted and the identification quality evaluation is done. The second part compares various types of the adaptive controllers with a non-adjustable PSD controller. The adaptive controllers are investigated from the various identification method point of view. The user graphic interface was realized for the identification and regulatory part. The time behavior of system responses after incoming disturbance and dynamic process changes during simulation systems control is compared with a physical model connected to B&R PLC. The comparison is done with the application of Matlab/Simulink program.
