Flutter is one of the most frequently encountered problems in aeroelasticity. Flutter control is therefore of great importance. It has been shown that flutter can be adequately modeled using a s...
Aerodynamics and Flight Control of Flapping Wing Flight Vehicles: A Preliminary Computational Study
Aerodynamics Flight Control Flapping Wing Flight Vehicles Preliminary Computational Study
2015/7/2
The dexterity and gracefulness of winged creatures have captured the imagination of humans for a long time. Insects have evolved sophisticated ight control mechanisms that permit a remarkable range of...
Carrier Differential GPS for Real-Time Control of Large Flexible Structures
Carrier Differential GPS Real-Time Contro Large Flexible Structures
2015/6/29
Current lab tests demonstrate vibration and orientation control of highly exible vehicles using only the GPS carrier to measure motion. A 30-foot long test structure has been constructed that is suspe...
The second part of this study examines the use of decentralized control strategies
to enable stable control of a platoon of vehicles in close formation. Energy
stability was proved for three di eren...
Computational Investigation of Wings with Miniature Trailing Edge Control Surfaces
Miniature Trailing Control Surfaces Wing
2015/6/18
Miniature trailing edge e ectors (MiTEs) are small
aps (typically 1% to 5% chord)
actuated with de
ection angles near 90 degrees. The small size, combined with little
required power and good cont...
Stabilization control of a hovering model insect: lateral motion
Hovering drone fly Lateral motion Flight stability Stabilization control Modal analysis
2012/2/29
Our previous study shows that the lateral disturbance motion of a model drone fly does not have inherent stability (passive stability), because of the existence of an unstable divergence mode. But dro...
A New Control Method for SSPS Orbital Transfer
Space Solar Power Systems Optimal Orbital Transfer Solae Electric Propulsion
2009/8/19
A new control method for the orbital transfer of the Space Solar Power Systems (SSPS) by the solar electric propulsion is presented. In this method, SSPS is launched from a place near the equator such...
