Imagine a world where aircraft monitor their structural health, twist their wings into optimal aerodynamic shapes, and actively control their own vibration, or a world where automobiles brace themselves for impact or actively adjust the ride and comfort for the passengers. Imagine a world where antennas alter their shapes and actively tune themselves. On a limited basis, often experimental, that is today's world. The technology that will enable many of the previously mentioned advances lies in the field of "Smart Structures". Smart Structures incorporates materials that have the ability to alter their performance in response to their surroundings. My work deals with various aspects of smart structures and intelligent systems. The projects discussed will include Adaptive and Intelligent Control of Systems, Modeling, Control of Mechanically Active Antennas, and the Control of Hybrid Electric Vehicles.
