Industrial PID controller with visualization and bumpless switching
Kupčík, Michal ; Chomát, Luděk (referee) ; Pivoňka, Petr (advisor)
This work informs reader about different program implementation of PID controller. Next it contains description of four basic events, which cause bump switching. For each of these four events is made analysis, why bump is caused and subsequently is made description, how to eliminate these bumps. The result is set of equations, which properly adjust regulators parameters. On big number of graphs there is proved, that after application of these equations, switching become bumpless. Another part of this dokument is a description, how to illustrative demonstrate bumpless switching in MATLAB's script, in B&R's virtual control system AR000 and on real system, whitch will be controled by B&R's control system type Power Panel.

Transfer and utilization of process data (PLC) in production control system
Kupčík, Michal ; Michal, Novotný (referee) ; Pásek, Jan (advisor)
This work explains to reader the difficulty of production scheduling and why is much advantageous using proper system for this work. Next he reads about complexity of production management and about necessity of linkage between all levels of company’s IT systems. We are going to use three different approaches for getting Siemens controller’s data out and for two of them we are going to describe general procedure, how we gets a data files, which are openable in classic table processor like MS Excel and which contain user’s choosen variables including their actual values. Finally reader will be familiarized with SimRead program, which serves for reading variable’s values in combination with Simatic standart communication blocks.
