Modeling and analysis of laboratory rotational pendulum
Nedvědický, Pavel ; Bastl, Michal (referee) ; Brablc, Martin (advisor)
This bachelor thesis aims at modelling, identification and control of Furuta pendulum. System was described via mathematical equations and simulation model was created in Matlab/Simulink. Parameters of rotary inverted pendulum were estimated using the simulation model. Then the thesis deals with swing up via torque impulse, energy control and PD regulator. In the part dealing with friction five compensation models were created. They include change of friction during rotation and one of them is dynamic model, Reset Integrator. Models were verified by adding them as an input to an actuator and testing them. To stabilize pendulum in inverted position state feedback control with state observer was designed using LQR method. Final regulation included all knowledge obtained during this thesis.

Control Rotational Inverse Pendulum Laboratory Model
Šnajder, Jan ; Bastl, Michal (referee) ; Brablc, Martin (advisor)
Aim of this bachelor thesis is modeling, identification and control of rotational inverted pendulum. The thesis describes parts of real system and its control. The work also contains creation of simulation model in Matlab/Simulink. Simulation model is respresented by mathematical equations created by second type Lagrange equations. Estimation of parameters is based on reduced systems and these parameters have been validated. Control of system is based on state-space model. The paper includes description of linearization, design of state-space control created by LQR method and creation of state-space observer. The last part of the study is focused on state observer experiments, friction compensation by few static friction models and by adding noise to compensation.

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.

Modelling and control design of mechatronics systems on state-space
Ertl, Lukáš ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
This work is concerned with modeling of simple mechatronic’s systems in state space and with designing their controls. In work is described a method for constructing the state model of direct current motor with programs MATLAB/SIMULINK and NI LabVIEW. There is designed the control for realized model and this control is verified in simulation. Later are model and its control, verified on real system.
