Modeling of electrical drives on the CompactRIO platform using FPGA
Kozumplík, Karel ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
This Master´s thesis engage in modeling of electric motions on CompactRIO platform with FPGA. Permanent magnet synchronous motor (PMSM) is namely described, modeled and tested here. This thesis demonstrates the complete work procedure for modeling of electric motion and testing behavior of motor in real time. Various types of discretization are described here and model si discussed from accuracy same as from FPGA utilization point of view. The last part of this project describes testing comparison between created model and real PMSM motor and results from this testing.
Algorithms of Model based Electrical Drives Monitoring and Diagnostics
Kozel, Martin ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
The aim of this thesis is to investigate PMSM models with internal faults. Two fault models are introduced. One of them is suitable for simulation of stator winding inter-turn short fault in case of one pole-pair motor and other one for simulation of inter-turn fault in case of multiple pole-pair motor. There are described some methods for model based fault detection of internal faults and sensor faults.
Sensorless control of AC motors on STM32 platform
Soviš, Jiří ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
The thesis is focused on the issue of sensorless vector control of a synchronous motor with permanent magnets in the low-speed range. In the first part, there is a brief description of the synchronous motor and the necessary transformations for the application of vector control. This is followed by the overview of sensorless methods for position estimation by injecting a high-frequency harmonic signal. The practical part is devoted to the implementation of a control algorithm to develop kit STM32NUCLEO-L476RG, which is preceded by the identification of all engine parameters. As part of the implementation, a structure including current, speed and position control was designed. The functionality and robustness of the settings have been successfully tested due to the different inertia and load.
Linear motor modeling and identification
Cimburek, Václav ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
This bachelor’s thesis deals with the creation of a model of a synchronous linear motor with permanent magnets, parameter identification and model visualization. The model includes variable inductances of d and q windings and variable motor force constant. A cascade control using P and PI controllers and dynamic decoupling is implemented to control the model. The whole system is simulated in the Simulink environment. In conclusion are evaluated the factors that may cause inaccuracies and improvements that could be done.
Modeling and control of rear driven axle for Formula Student
Kavec, Matúš ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This thesis is focused on design of controll structure of Formula Student monopost. Part of the thesis is a design and subsequent debgging ofthe model so it has the best possible response compared to reality. A PID controller with two degrees of freedom was used to create the control structure. Created controll structure has the task of regulating the system to the required value. By reducing skid, which is often unwanted in race cars, we can achieve better response while accelerating.
Parameter Identification of DC Motors
Kabelka, Ondřej ; Veselý, Libor (referee) ; Buchta, Luděk (advisor)
This bachelor´s thesis adress the issues of DC motor identification. It also adress the controlling of this motor and creation of current loop regulator and its implementation. Part of the thesis is also laboratory task, which deals with this topic.
Water mixer
Damajka, Štěpán ; Glos, Jan (referee) ; Veselý, Libor (advisor)
The aim of this bachelor thesis is to build device for mixing warm and cold water. Water mixer consists of a temperature sensor and flow sensor. Actuator devices are two-way diaphragm solenoid valves and three-way valve with servo-engine. Thesis focuses on identification system and design of a suitable controller.
Laboratory tasks for Feedback 38-001
Gléba, Gergely ; Veselý, Libor (referee) ; Blaha, Petr (advisor)
The aim of this project was to get acquainted with the preparation Feedback 38-001, regenerate and establish several demonstration tasks. The first part deals with the description and the resurgence of the device. The second section describes the activities of modernization and innovation the teaching facilities. The main care was to focus on the implementation of connection with the computer supplementing measuring card and obtaining information of the regulation in real time. The third part includes the proposed laboratory tasks. The first task is based on the on-off control, which is mostly used in practice for its ease of use, with no major claims. The second task is defined for continuous control, which ensures better quality and comfort of controlling the level and the water flow. The third contains a task for identification of system parameters.
Design of control board for BLDC motor
Zbranek, Petr ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
In the context of this master’s thesis are solved algorithms and hardware for control BLDC motor. The first was designed algorithm in LabView called "six-step". This algorithm causes a torque ripple, so in the final version was used vector control. It is a sensor control, so was necessary to design a measurement of rotor position. It was solved using a magnetic position sensor. After testing the control algorithm was designed my own hardware for control the BLDC motor. The main control unit was chosen microprocessor MC56F82743, which is designed specifically for BLDC motor control. The microprocessor was programmed in the CodeWarrior development environment, using a JTAF and USB-TAP.
Control of electric drives using Simulink Real-Time
Schrötter, Ján ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
The goal of this bachelor’s thesis is implementation of control of permanent magnet synchronous motor using Simulink Real-Time on a platform with MF624 I/O card. The control will be realized by hardware-in-the-loop simulation method. The thesis deals with structure of the motor and transformations needed for vector control. The platform and control system of the whole task is described in the next part of the thesis.
