Controllers design for plants with large time constants
Omelka, Vlastimil ; Rojka, Aleš (referee) ; Davidová, Olga (advisor)
This bachelor thesis aims to present a design of convenient continuous action controllers for plants. A brief summary of methods of design mostly in use is listed in the work. Selected methods are presented with more detailed description and are applied on four particular systems with different time constants. Furthermore the calculated values are being processed using MATLAB - Simulink program. The final readings are evaluated and compared with respect to the quality and precision of the regulation.

Controllers design for plants with small time constants
Rozmahel, Ivan ; Rojka, Aleš (referee) ; Davidová, Olga (advisor)
The main reason of this project is to set up and to propose continous controllers for process with small time responses. The regulated circuits with different type of regulators and its different settings were proposed in this project. These parameters were set up with method synthesis. These calculation were compared and evaculated as regards to control accurancy and quality.

Sample tasks for automation education
Dočekal, Aleš ; Rojka, Aleš (referee) ; Davidová, Olga (advisor)
The aim of this bachelor tesis puts mind to the problem of forming combinational and sequential logic circuit tasks. These demonstrational tasks will be used in the educational system for the subject automation. To design the tasks was used the program LOGO!Soft Comfort . Verification of proper running was done by the programmale logic controller LOGO! 0BA5.

Sample tasks for automation education
Sileská, Silvia ; Janečka, Jan (referee) ; Davidová, Olga (advisor)
This bachelor´s thesis deals with the design and demonstration of tasks addressing combinatorial and sequential logic circuits. To resolve the assignment must be familiar with the theory of logical management, with program LOGO!Soft Comfort and issue of programmable controllers. Overall, the proposed six tasks are solved by basic rules for use in a logical management. Finally, it was necessary to verify the proper functioning of the proposed tasks, which it realized by using LOGO!Soft Comfort and programmable logic computers. The proposed tasks will serve as a demonstration tool for teaching the subject of automation.

Minimisation of Logical Functions
Horký, Miroslav ; Davidová, Olga (referee) ; Šeda, Miloš (advisor)
For minimisation of logical functions, laws of the Boolean algebra and the Karnaugh maps are mostly used. However, use of Karnaugh's maps is based on visual recognition of adjacent cells for functions with no more than 6 variables and, therefore, the method is not suitable for automated processing on computers. A direct application of the Boolean algebra laws is not restricted in this way, but there is no general algorithm defining the sequence of their application and thus this approach is not suitable for computer implementation either. The well-known method usable on computers is the algorithm proposed by E. J. McCluskey and W. Orman Quine.

Non-oscilllating plants control with dead time
Plíšek, František ; Švarc, Ivan (referee) ; Davidová, Olga (advisor)
This bachelor thesis deals with the selection of methods which are suited for the determination of continuous and numerical controller parameters if a non-oscillating plant is directed with a transportation lag, description of these methods, their application on the design of a continuous and numerical control system. In conclusion, the graphic evaluation of the results is done on the basis of the control process and evaluation in terms of accuracy and control quality.

Catalog of standard logarithmic frequency characteristics
Velecký, Pavel ; Švarc, Ivan (referee) ; Davidová, Olga (advisor)
One of the options how to suggest the parameters of the continuous action controller is to use a method of standardized logarithmic amplitude frequency characteristic. It is a frequency method based on the choice of the form of standardized logarithmic amplitude frequency characteristic of open control circuit. I have created a catalogue of standardized logarithmic frequency characteristics in order to facilitate the work while using this method.

Algebraic methods of control for discrete control circuit design
Jurča, Petr ; Švarc, Ivan (referee) ; Davidová, Olga (advisor)
The bachelor essay deals with discreet regulation circuits where it is possible to use either a regulator with fast laid textures or a universal regulator. To propose an optimal regulator it is possible to use various algebraic proceeding methods which polynomial. In case of unidimensional task I converted the synthesis of discreet optimal control to solving inexplicit (Diophantine) polynomial quadratic which is possible to solve by various methods.
