Adaptivní řízení veřejného osvětlení
Janiga, Peter ; Gašparovský, Dionýz ; Barčík, Michal ; Lipnický, Lukáš
Public lighting is a specific type of lighting system, which various requirements. It is a lighting system which is subject to many influences. Some impacts are changing very rapidly but a lighting system is designed for a specific case. These effects are for example traffic density, conflict situations and the impact of weather. Comprehensive regulation taking into account all the effects not currently exist but particular systems taking into account the subtasks are occuring. Paper describes possible ways to control lighting systems based on current conditions. The aim is to show the possibilities and also the technical prerequisites for the realization of such systems. Described technology is currently in its early stages and pilots projects are preparing. Aim of this paper is give information about technology and open discuss about adaptive public lighting.

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 control of small brewery
Kalivoda, Jakub ; Jelínek, Aleš (referee) ; Kopečný, Lukáš (advisor)
This final thesis deals with adaptive control of small brewery. Contains a short description of brewing technology and adaptive control. Includes design of small brawery and control system based on STM32F407 Cortex-M4 microcontroller. For online identification is used Recursive Least Squares Method. The controller function perform a modified PSD controller with filtered derivative component, reducing the first overshot and dynamic antiwindup. The proposed adaptive controller is implemented into microcontroller. Created device i used for semi-automatic beer production.

Methods for parameters setting of controller by plane with flight control with floating level centre in MATLAB-Simulink
Náglová, Katarína ; Burlak, Vladimír (referee) ; Pivoňka, Petr (advisor)
The thesis is focused on aircraft flight level control in case when the location of center of gravity changes during flight. The theoretical part of the thesis describes basics of aerodynamics, which are necessary to understand airplane's behavior and its control theory. Basics of state theory and stability of systems, as it is used for design of linear model. This part also mentions mathematical equations of nonlinear model of business jet and discusses conventional and adaptive methods used to design autopilot parameters. Several autopilots were designed in practical part of the thesis. The most important part is the logic used to determine location of center of gravity of the airplane. The models use nonlinear model of an airplane that better represents the real environment and conditions.

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.

Zajištění spolehlivé činnosti adaptivního LQ regulátoru
Böhm, Josef
Adaptive LQ controllers can exhibit uncorrect behaviour at the beginning of the adaptation process. Paper presents an approach which can overcome the problem. It is proposed to operate LQ adaptive controller jointly with some fixed robust controller, typically a PID one. Using single tuning knob, it is possible to tune adaptuve controller properties from that of PID to a standard LQ controller ones.

Adaptivní prediktivní LQ řízení s omezením
Böhm, Josef
Controller design for real systems must consider levels of signals in the system. This contrasts with the most design techniques that are based on linearity assumption. The Model predictive control (MPC) is a technique able to consider desired levels of signals. Paper deals with the situation in LQ controller design. It is shown that the latest results in MPC control can be also considered as an LQ approach.
