Estimator in control systems with variable structure
Dvořáček, Martin ; Mikšánek, Vojtěch (referee) ; Pivoňka, Petr (advisor)
The thesis write about the linear discrete time incremental estimators. These are used for the choice of the best control system in systems with variable structure and further for direct control with status controller. There is an application of this on physical plane. In this paper PID variation controllers are discussed and optimized using Nelder-Mead Simplex Method. Feedback control with optimal PID is compared with control using linear discrete incremental estimators and status regulator.

Control Design of the Rotation Inverted Pendulum
Cejpek, Zdeněk ; Němec, Zdeněk (referee) ; Matoušek, Radomil (advisor)
Aim of this thesis is building of a simulator model of a rotary (Furuta) pendulum and design of appropriate regulators. This paper describes assembly of a nonlinear simulator model, using Matlab–Simulink and its library Simscape–Simmechanics. Furthermore the paper discuss linear discrete model obtained from the system response, using least squares method. This linear model serves as aproximation of the system for designing of two linear discrete state space regulators with sumator. These regulators are supported by a simple swing–up regulator and logics managing cooperation.

Control of Quadrotor
Tesáček, Zdeněk ; Grepl, Robert (referee) ; Šolc, František (advisor)
This master’s thesis deals with the design and optimization of the quadrotor stabilization control. The basic physical properties and technical aspects of this specific device are illustrated using the NANOKOPTER platform. Dedicated mathematical model of quadrotor was implemented in MATLAB/Simulink environment to emulate the behavior and characteristics of real quadrotor. Based on this model a feasible method of stabilization control by means of state controller was conceived and developed. The proposed solution utilizing state controller was incorporated into the stabilization control procedures of the NANOKOPTER testing platform and its functionality successfully verified during field trials.

Optimization of the DC motor state space controller for FPGA
Maliszewski, Michal ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
This thesis deals with the optimization of state space controller of DC motor on FPGA in LabVIEW environment on NI cRIO platform. In the first part, the state space model of the given DC motor is presented in Matlab/Simulink and then the position feedback controller with steady-state error elimination and with state observer with error compen-sation using LQR method is designed. The thesis continues with transforming the con-troller to LabVIEW environment where the code is edited for FPGA use. Next, the fo-cus on FPGA hardware resources consumption optimization leads to careful work with fixed-point data type. After successful code compilation on target hardware, the real given DC motor is connected and the series of tests are performed. The output of the thesis is working state space controller running on FPGA and the graphical user inter-face on real-time host cRIO, which enables the user to control the plant and save the data on the disk.

Control of Magnetic Levitation Educational Model
Bednařík, Josef ; Brablc, Martin (referee) ; Matějásko, Michal (advisor)
The bachelor thesis deals with the modelling and control of the magnetic levitation CE 152 laboratory plant, which is specific in its nonlinearity and unstability. Firstly, all parts of the system are described by mathematical equations, which are the basis of the modelling of simulation model created in MATLAB/Simulink. Estimation of parameters is tackled by using the various of experiments and simulation’s model is validated with the real magnetic levitation system. Main body of the paper is focused on description and aplication of control on simulation’s and real model. It is realized by PID regulator, state regulator and feedforward regulator. In the last part of the thesis, the results are evaluated and compared among the all methods of control.

Educational Model - Balancing Rod
Pojsl, Jakub ; Rajchl, Matej (referee) ; Najman, Jan (advisor)
This master's thesis deals with the design of the educational model of a balancing stick and implementation of control algorithms for this model. The balancing stick combines an inverted pendulum with reaction wheels, which allow for momentary control and maintaining its balance. The thesis includes a theoretical analysis of the reaction wheels, research on suitable components for the model's realization, design and construction of the physical device, implementation and testing of the control algorithms and evaluation of the design of the real model. The outcome of the thesis also includes a set of tasks that complement the educational use of the model and documentation of the control unit library.
