- Addresses challenges in modeling and stabilityPractical Considerations
This program explores the use of piezoelectric transducers (piezos) for controlling mechanical motion and damping vibrations in flexible structures. Piezoelectric materials generate a voltage when subjected to stress, allowing them to act as sensors to detect vibrations or as actuators to introduce counter-forces. The coursework covers the fundamental physics of the piezoelectric effect, both direct (stress to voltage) and converse (voltage to stress). It details how these materials are integrated into devices for vibration control, focusing on methods like feedback circuits and electrical shunting. The program delves into practical implementations, including collocated sensor/actuator pairs and more advanced self-sensing systems where a single piezo element functions as both sensor and actuator. It also examines passive shunting circuits (like RL shunts) for dissipating vibrational energy and discusses their limitations, particularly in scaling to multi-mode damping. The challenges of accurately modeling piezo capacitance and managing feedback loop stability are also key aspects covered.
