Mathematical model of a climatic chamber
Hort, Tomáš ; Bartík, Ondřej (referee) ; Veselý, Libor (advisor)
The objectives of this bachelor thesis are designed and verification matchematical model climatic chamber - incubator. In the beginning, the I2C communication bus is decribed. Then, the humidity and temperature sensors are analysed. Measuring and controling system CompactRio is used for processing data, program Labview is used for programming. Identification of system and designing matchematical model is accomplished in System Identification Toolbox. In the next part, the methods of heat transfer are discussed. The thermal analysis of the system was used to build a physical model in Simulink - Simscape Thermal. The last chapter is focused to the creation of a compact datalogger designed for long-term recording of measurements in an incubator.
Motion control of an aileron
Kotrlý, Michal ; Kozubík, Michal (referee) ; Veselý, Libor (advisor)
This bachelor’s thesis aims to design, assemble and test an electromechanical model of an aileron with a dual actuator configuration that would verify used control algorithms. Mainly those that mitigate force fight between actuators and reduce mechanical stress affecting lifespan of the aileron. Algorithms are implemented in a PLC which supplies power to actuators/sensors and controls the position and movement of the aileron.
Control of a rotational inverted pendulum
Bednář, Ladislav ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
The goal of this work is modelling and design of an inverted pendulum prototype. The work presents a mathematical model of a rotary pendulum, modelling of a BLDC motors and also a 3D model of the pendulum prototype is present. The work mentions design of the state space controller and swing up control of the inverted pendulum. Dynamics obtained from the mathematical model is used to create a 3D dynamic model of a pendulum, with the use of the Simscape toolbox. The work deals with control of a BLDC motors with use of vector control. The algorithm is implemented on the CompactRIO platform. Later, hardware is developed, containing STMicroelectronis microcontroller, capable of replacing the CompactRIO platform.
Pendulum stabilization
Maralík, Marek ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
The diploma thesis deals with putting the pendulum into upright position and its stabilization on a real system. The opening chapter describes the limiting various implementation inverse pendulums, the use of major laboratory tasks in industry, and the selection of appropriate methods for stabilization. The real system was properly identified and parameterized. The mathematical model of the inverse pendulum was derived using the Lagrange method of the second type, the nonlinear system was converted into a status description and linearized for the needs of the state controller design. The system was simulated in the Matlab Simulink environment. The LQR controller was chosen as the regulator stabilizing in upright cases. A Kalman controller in discrete form was prepared for the filter signal and estimation of residual states. The energy method was chosen for the upright pendulums. The proposed methods were tested and implemented in simulation and on a real system.
CompactRIO module for servomotor control
Macek, Daniel ; Bartík, Ondřej (referee) ; Veselý, Libor (advisor)
The thesis deals with the description of PMSM and BLDC motors as well as the way of their control. In addition, the thesis deals with the description of the instruments of National Instruments, DAQ, CompactRIO and PXI. The details of the user module's production in the CompactRIO device, both hardware and software, are specified in the paper. The following is a description of the proposed CompactRIO module.
Through of road II / 428 in Dětkovice
Veselý, Libor ; Kosňovský, Michal (referee) ; Smělý, Martin (advisor)
The diploma thesis deals with the design of the repair of the road II/428 in the village Dětkovice and with the construction of new sidewalks and parking spaces along this road. The aim of the thesis is to optimize the tracking of the road II/428 with a regard to the safety of using it, to ensure quality drainage of the road and to enable the construction of a new sidewalk. The designed sidewalk is going to increase comfort and safety of pedestrians in the village. The new parking spaces are going to improve situation with parking in the village.
Control of ball and plate system
Bednář, Ladislav ; Bartík, Ondřej (referee) ; Veselý, Libor (advisor)
The goal of this work is to design a control algorithm for position controlling of the ball on 2D plate with feedback implemented by camera. Frist part is devoted to the design of steper motor controller, that is controlled by analog inputs. Controller was tuned on CompactRIO platform later replaced with microprocessor by Freescale. PCB design for microprocessor board is included. Next we described controlled system by mathematical model, which we use for PID controller design. Mathematical model is designed in linear form and nonlinear form, which analyze nonlinearity of rolling friction. Image processing with control loop is contained in Matlab-Simulink workspace. At last, laboratory task is designed.
Identification of DC motor parameters
Kabelka, Ondřej ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This bachelor´s thesis deals with identification of parameters of the DC motor. An identification program in LabVIEW with data processing in Matlab has been created. After the identification of electrical and mechanical parameters of the motor there are current regulators and velocity regulators designed and implemented in the LabVIEW enviroment as a verification of the correctness of the identification.
Modeling and control of stepper motor in MATLAB/Simulink
Macek, Daniel ; Veselý, Libor (referee) ; Kozovský, Matúš (advisor)
The work deals with describing the types of stepper motors, as a method of their controlling, their potential method of modelling each type of motors. Main purpose was to design a model of stepper motor with controlling in open-loop for modes Full-step, Half-step and Microstepping and controlling in closed-loop. Resultant design model of stepper motor compare with real stepper motor.
Restoring of the ventilation shaft generator
Veselý, Libor ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
The subject of this work is the repair of an air-handling unit. Possible causes of the problem are analyzed and multiple solutions are proposed. The first variant considers the refurbishment of the damaged component using thermal spray technology, including the choice of the best method. The second solution proposes the manufacture of a new part using machining in the environment of the company. This process requires an intermediate product to be made, and the choice of the correct machines from what the company has available, choice of the right tools and cutting conditions. The technical-economical evaluation compares the the expenses tied with both of the solutions. The chosen repair solution was used for the repair of the air-handling unit.
