In this dissertation, a new adaptive harmonic selective detection algorithm is proposed for power quality improvement applications. The adaptive gains of the proposed method can be chosen relatively large to obtain faster convergence....
Many leg controllers and gaits have been designed directly with lower level parameters. This approach can lead to very high performance gaits, but can also lead to platforms highly tuned for one particular application with drastically...
High-speed impinging jets are often generated by the propulsive systems of aerospace launch vehicles and tactical aircraft. In many instances, the presence of these impinging jets creates a hazard for flight operations personnel due to...
In response to the increasing demand for jet noise studies performed at realistic conditions, the Florida Center For Advanced Aero-Propulsion at Florida State University has recently brought online an upgraded Anechoic High-Temperature...
Humans and terrestrial legged animals can travel with great degree of stability, agility and maneuverability over a large number of terrains such as gravel, grass, sand, rock, mud, snow, asphalt, river-beds and more. They can also...
The electric power systems in U.S. Navy ships supply energy to sophisticated systems for weapons, communications, navigation and operation. The reliability and survivability of the shipboard power systems (SPS) are critical to the...
The study of supersonic cavity flows is of interest both from fundamental fluid dynamics and practical perspectives. The complex nature of this flowfield, consisting of compressible shear layers, compression/expansion waves, and fluid...
Superfluid 4He (He II) has been widely used as a coolant material in many engineering applications. Its unique heat transfer mode is the so-called thermal counterflow. The study of thermal counterflow will contribute to the design of He...
In this study, the flow and acoustic field characteristics of dual high-speed axi-symmetric impinging jets will be examined. Initially, the short takeoff and vertical landing (STOVL) facility was redesigned by adding a second jet to the...
Unsteady actuators with a high amplitude output and tunable frequency are needed for the effective and efficient control of many sub and supersonic flows. The development, design, characterization, modeling and implementation of a novel...
Animals have demonstrated that legged locomotion can provide an efficient, rapid and robust means for traversing natural and artificial terrains and obstacles while employing several distinct locomotion modalities. This has led...
The main goal of this thesis is to present a power control module (PCON) based approach for power and energy management and to examine its control capability in shipboard power system (SPS). The proposed control scheme is implemented in...
The proliferation of semiconductor-based nonlinear devices in modern power systems has caused serious concern over the power quality problems. This dissertation proposes a control strategy to coordinate multiple active front-end...
