In the modern era, it is of utmost importance to develop methods for energy production and vibration damping without depleting resources or overburdening structures. Various studies have highlighted the significance of piezoelectric materials, which serve dual functions as sensors and actuators. This thesis focuses on developing vibration damping techniques using shunted piezoelectric circuits. The use of piezoelectric materials for vibration control allows the conversion of mechanical energy from vibrations into electrical energy, which can then be dissipated through appropriate shunted circuits. The system under study is modeled and simulated in the time domain, and its response provides data on the efficiency of the investigated damping methods. Efforts are made to actively control the system’s vibrations, aiming for immediate adaptation for more efficient vibration control. Additionally, a fuzzy logic controller is developed to enhance this effort, combined with shunted circuits to provide a degree of adaptability. Subsequently, the damping methods are compared to formulate more efficient solutions. In conclusion, this work contributes to the understanding and improvement of the efficiency of vibration damping systems using piezoelectric materials, as well as to better real-time vibration control, with a degree of adaptability required. It aims to offer directions for future research in this field.
