Master's thesis

Abstract:

The present work shows the creation, advancement, and practical confirmation of an output control system specifically designed to regulate particular components in the manufacturing processes of electric cars (EVs). This system is designed to improve the effectiveness and efficiency of electric vehicle (EV) manufacturing, based on ideas from feedback control theory. Its goal is to contribute to the progress of the industry. The thesis develops a correlation between theoretical design and practical execution through systematic testing and improvement, thereby bridging the divide between academics and industry. The approach includes an extensive review of existing literature, the creation of a theoretical design, the development of a prototype, the testing of the prototype using empirical methods, the analysis of the resulting data, the refinement of the methodology based on the analysis, and the validation of the final version. The simulation testing validates the functioning of the control system by exhibiting its capacity to accept signals, calculate vehicle trajectories, assign control values to motion actuators, and adhere to motor and braking limitations. Test scenarios demonstrate the system's ability to effortlessly attain specified speeds, minimize overshooting, and seamlessly incorporate Steer-by-Wire (SWA) technology. An important finding is that the weighting matrices have a substantial impact on the performance of the control system, emphasizing the need for meticulous design considerations. When it comes to selecting software for implementing the EAST-ADL paradigm, there exist problems. However, Enterprise Architect is considered the preferable solution due to its stability and user-friendliness. Ultimately, the empirical verification of the suggested control system affirms its viability and applicability in real manufacturing environments. This thesis makes a valuable contribution to the continuous development of electric car manufacturing by improving manufacturing processes and increasing the efficiency of control systems. These advancements are crucial for advancing towards a future of sustainable transportation.
