Design and Build of Swarm Quadrotor UAVs at UGS

At the University of Glasgow, we have been developing the swarm of autonomous micro-unmanned aerial vehicle (?-UAVs), as a part of team projects of the final yearproject design course: Aerospace Systems Design Project 4for our BEng in Aerospace Systems program. For our Singapore campus, where similar course is conducted, the platform chosen is...

Towards Estimation and Correction of Wind Effects on a Quadrotor UAV

In this paper the problem of estimation and correction of wind effects on a quadrotor UAV, without using wind sensors, is discussed. A large body of research addresses the effects of wind on a quadrotor, however most of them consider it only as a disturbance in their control loop and, for this reason, they solved the problem compensating for the...

Post-buckled precompressed (PBP) subsonic micro flight control actuators and surfaces

This paper describes a new class of flight control actuators using Post-Buckled Precompressed (PBP) piezoelectric elements to provide much improved actuator performance. These PBP actuator elements are modeled using basic large deflection Euler-beam estimations accounting for laminated plate effects. The deflection estimations are then coupled...

Post-buckled precompressed (PBP) elements: A new class of flight control actuators enhancing high-speed autonomous VTOL MAVs

This paper describes a new class of flight control actuators using Post-Buckled Precompressed (PBP) piezoelectric elements. These actuators are designed to produce significantly higher deflection and force levels than conventional piezoelectric actuator elements. Classical laminate plate theory (CLPT) models are shown to work very well in...
