Optimal Vibration Suppression Using On-line Pole/Zero Identification
… perform very precise tasks or maneuvers require controllers to compensate for their inherent structural flexibility. Many of these applications involve structures that have time-varying dynamics, or have dynamics that are not considered in the traditional off-line controller design. These types …

Actuator Optimization and Control of Pediatric Knee Exoskeleton for Community-based Mobility Assistance: More Lightweight, More Affordable, and More Stable
… and mass but also cause a small range of stable controller gains.</p> <p>To facilitate pediatric exoskeleton in community settings, firstly, we proposed an actuator optimization framework that identified the optimal design parameters for both motor and transmission while minimizing the actuator …

Feedback control of oscillations in combustion and cavity flows
This thesis considers the control of combustion oscillations, motivated by the susceptibility of lean premixed combustion to such oscillations, and the long and expensive development and commissioning times that this is giving rise to. The controller used is both closed-loop, employing an actuator …

Discrete-time control of a spacecraft with retargetable flexible antennas
This dissertation considers the discrete-time control of a spacecraft consisting of a rigid-platform with retargetable flexible antennas. The mission consists of independent minimum-time maneuvers of each antenna to coincide with pre-determined lines of sight, while the platform is stabilized in an …

Macro-Fiber Composites for Sensing, Actuation and Power Generation
… themes, sensing and actuation for vibration control, and power harvesting. The MFC is constructed using piezofibers embedded in an epoxy matrix and coated with Kapton skin. The construction process of the MFC affords it vast advantages over the traditionally used piezoceramic material. The …
