This research centers on the analysis and design of intelligent structures that can adapt and/or compensate for unwanted stimuli to better improve the performance of the system (e.g. reduced vibration, increased stability, improved surface precision). This work involves exploring advanced actuator and sensor technology along with novel control methodologies to provide adaptability, robustness, and intelligence to the system.
Smart materials are materials that undergo transformations in a controlled fashion by external stimuli, such as stress, temperature, electric or magnetic fields. Some examples include piezoelectric materials, shape-memory alloys, magnetorheological fluids, and electro-active conductive polymers. This research involves the analysis, design, and application of smart materials for control and sensing of structures.
AOE 3034 - Vehicle Vibration and Control
Course focuses on the mathematical modeling and response methods of dynamic systems with an emphasis on mechanical systems. The course presents the transfer function approach and state space methods for the modeling of dynamic systems and employs time and frequency domain analysis methods for studying the system response. The course also focuses on classical methods of feedback control system design, including root locus, Bode, and Nyquist methods.
