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.

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.

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).

Model of the Water Level Control
Karola, Ladislav ; Dokoupil, Jakub (referee) ; Chomát, Luděk (advisor)
The Bachelor’s Thesis deals with problem of water level control. Author de-sign the simulation of a real technologic process. Thesis is analyzing mathematic model of system. Mathematic model is realised in Simulink. Next point is built a model, which simulates this real technologic proc-ess. There is implemented microchip ATMega16. Thesis includes descriptions of model parts. Model is controlled with Power Panel 400 series by B&R Company. Project also contains a Visualisation of technologic process. The last points of Thesis are comparison of theoretic data with real data, com-pilation of a brief manual of model and instruction for laboratory work.
