Enhancement of Vehicle Dynamics Through Adaptive Torque Vectoring Control with PMSM Powertrain
Šimanský, Sebastian
This paper presents an adaptive control torque vectoring algorithm designed for enhancing vehicle dynamics and stability through precise manipulation of individual wheel torques. The algorithm utilizes the vehicle’s yaw rate as the primary input parameter to dynamically adjust the torque distribution among the wheels, thereby optimizing the usage of traction, overall manoeuvrability, and handling performance. By integrating adaptive control techniques, the proposed algorithm continuously adapts to varying driving conditions and vehicle dynamics, ensuring robust and effective torque vectoring across a wide range of scenarios. Lastly, the functionality of the developed algorithm is demonstrated through simulations with various driving scenarios.
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.

Tato práce je zaměřena na výzkum moderních metod automatického řízení letu a jejich ověření s ohledem na současný stav poznání a budoucí využití bezpilotních letadlových systémů. Práce představuje proces návrhu automatického systému řízení letu s důrazem na přístupy z oblasti návrhu založeného na modelování (Model-Based Design). Nedílnou součástí tohoto procesu je tvorba matematického modelu letounu, který byl využit k syntéze zákonů řízení a k vytvoření simulačního rámce pro evaluaci stability a kvality regulace automatického systému řízení letu. Jádro této práce se věnuje syntéze zákonů řízení založených na unikátní kombinaci teorie optimálního a adaptivního řízení. Zkoumané zákony řízení byly integrovány do digitálního systému řízení letu, jenž umožňuje vysoce přesné automatické létání. Závěrečná část práce se zabývá ověřením a analýzou navrženého systému řízení letu a je rozdělena do 3 fází. První fáze ověření obsahuje evaluaci robustnosti a analyzuje stabilitu a robustnost navrženého systému řízení letu ve frekvenční oblasti. Druhá fáze, evaluace kvality regulace, probíhala v rámci počítačových simulací s využitím vytvořených matematických modelů v časové oblasti.  V poslední fázi ověření došlo k integraci navrženého systému řízení letu do experimentálního letounu, sloužícího jako testovací platforma pro budoucí bezpilotní letadlové systémy a jeho evaluaci v rámci série letových experimentů.
Adaptive controllers with principles of artificial intelligence
Pitra, Michal ; Malounek, Petr (referee) ; Pivoňka, Petr (advisor)
The diploma thesis is focused on an adaptive control, especially in a self-tuning controller area. The thesis is divided into two main parts. The first part deals with identification methods of the adaptive control. The recursive least squares algorithm and the neural network method are the most popular identification methods. These methods are contrasted and the identification quality evaluation is done. The second part compares various types of the adaptive controllers with a non-adjustable PSD controller. The adaptive controllers are investigated from the various identification method point of view. The user graphic interface was realized for the identification and regulatory part. The time behavior of system responses after incoming disturbance and dynamic process changes during simulation systems control is compared with a physical model connected to B&R PLC. The comparison is done with the application of Matlab/Simulink program.
