Recently, there has been growing interest in developing unmanned aircraft systems (UAS)
with advanced onboard autonomous capabilities. This paper describes the current state of …

This paper considers the problem of obtaining good attitude estimates from measurements
obtained from typical low cost inertial measurement units. The outputs of such systems are …

Autonomous helicopter flight is widely regarded to be a highly challenging control problem.
Despite this fact, human experts can reliably fly helicopters through a wide range of …

Helicopters have highly stochastic, nonlinear, dynamics, and autonomous helicopter flight is
widely regarded to be a challenging control problem. As helicopters are highly unstable at …

Autonomous helicopter flight is widely regarded to be a highly challenging control problem.
This paper presents the first successful autonomous completion on a real RC helicopter of …

We show that for an adaptive controller that uses recorded and instantaneous data
concurrently for adaptation, a verifiable condition on linear independence of the recorded …

This paper considers the question of using a nonlinear complementary filter for attitude
estimation of fixed-wing unmanned aerial vehicle (UAV) given only measurements from a …

We consider the problem of system identification of helicopter dynamics. Helicopters are
complex systems, coupling rigid body dynamics with aerodynamics, engine dynamics …

This paper considers the problem of obtaining high quality attitude extraction and gyros bias
estimation from typical low cost intertial measurement units for applications in control of …

We present a system consisting of a miniature unmanned aerial vehicle (UAV) and a small
carrier vehicle, in which the UAV is capable of autonomously starting from the moving …
