Torque Vectoring Implementation for Formula Student Monopost
Šimanský, Sebastian ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
This work deals with the design and implementation of an algorithm for adaptive torque vectoring, which is specifically designed to enhance vehicle dynamics and stability. This algorithm manipulates the torques of each wheel based on the vehicle’s angular velocity, allowing for optimization of traction and improvement in agility and control. By utilizing adaptive control strategies, the algorithm automatically adjusts to changing conditions and vehicle characteristics, ensuring efficient torque distribution in various driving situations. The functionality of the algorithm is further demonstrated through simulations, and the required algorithm model is implemented on the main control unit of a Formula Student race car via automatic code generation. The final outcome includes testing on a physical race car and evaluating the algorithm’s contribution to vehicle dynamics.

Fractional-order derivatives and integrals in PID controllers of PMSM drives
Hromek, Vít ; Veselý, Libor (referee) ; Zezula, Lukáš (advisor)
This bachelor thesis focuses on the control of a permanent magnet synchronous motor (PMSM) with a fractional order PI controller (FOPI). Using vector control, the current components are decoupled ("decoupling") and controlled individually. PI controllers are then designed on these current components, which are replaced by FOPI controllers in the later part of the paper, and the quality of the control is evaluated using the quadratic integral criterion and the ITAE criterion. Similarly, a fractional order controller is also wound for speed control. The last part of the work is focused on plotting the results for different parameters. There is no improvement in the quality of current and speed control using fractional order controller over the conventional controller.

An optimal strategy for transporting objects between moving conveyor belts
Vítek, Pavel ; Friml, Dominik (referee) ; Veselý, Libor (advisor)
This thesis deals with strategies used in pick-and-place applications. In the theoretical part, the main parameters of the robot-conveyor system, such as efficiency and gripping rate, are first described. Subsequently, pick-and-place problems are divided into solutions with one or more robots. Then, the paper focuses on well-known strategies such as FIFO or SPT. The construction of a cost function based on the position of an object on the conveyor is described. Furthermore, the creation of the simulation is described, which is then compared to the B&R solution. Then, the different strategies in different scenarios are analysed. Finally, the rules for the selection of strategies are formulated and the whole paper is summarized.

Servo-drive control by Zedboard platform
Kozumplík, Miroslav ; Bartík, Ondřej (referee) ; Veselý, Libor (advisor)
The Master`s thesis deals with the creation and implementation of a servo drive control using the Zedboard platform. The aim of the thesis is to describe the method of Field-Oriented Control of synchronous motor with permanent magnets. The FOC algorithm is implemented by using an automatic IP Core generation for the FPGA in the Zynq-7000 SoC. A printed circuit board is designed to interface the Zedboard platform with a real PMSM servo drive. The designed PCB contains a two-level voltage invertor composed of MOSFET transistors, Hall probes for measuring the current through the motor phases and other elements necessary for the control and feedback of the PMSM motor controlled by FOC and SVPWM algorithm.

Control of PMSM drive Formula Student
Kavec, Matúš ; Kozovský, Matúš (referee) ; Veselý, Libor (advisor)
This thesis describes the basic function of a vector control of permanent magnet synchronous motors, the operation of a torque-maximizing algorithm that extracts the maximum torque from the current value. It further describes the operation of the field weakening algorithm that allows the motor to spin above a nominal speed. Characteristic curves for a motor with an embedded permanent magnets have been developed in this work. Based on these curves, the various algorithms required for the vector control were developed. The algorithms were created in the Simulink environment, which allows the model to be exported to HDL code and IP cores for a programmable gate array. Functional IP core blocks were connected in the Vivado environment to create the vector control. The resulting design used 49 digital signal processing modules.

High frequency signal injection method for PMSM position estimation
Moravec, Vojtěch ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This thesis is focused on the design of vector control of interior permanent magnet synchronous motors. The first part of this work deals with vector control transformations and mathematical modelling of synchronous motors. Furthermore, algorithms of sensorless control are discussed, especially HF injection sensorless methods. One of these methods was used for torque and speed control. Problem of phase delay caused by filters and it’s compensation is also discused. One of the HF injection sensorless method was implemented on both motors. The results of simulations in MATLAB/Simulink and tests of real motors on dSpace are included.
