Neural network based control of a four rotor helicopter

In-flight collision avoidance controller based only on OS4 embedded sensors

“…In order to compensate the Coriolis and gyroscopic torques, they used PD and PD 2 controllers. Dunfied et al (2004) developed an artificial neural network based controller to take-off, hover, and land. Guenard et al (2005) proposed the use of an intuitive strategy based controller for taking-off and landing.…”

Modeling and control approach to a distinctive quadrotor helicopter

“…The first type is shown in [12], which neglected the air friction and the gyroscopic effects resulting from both the rigid body rotation and the propellers rotation. The second type neglected the gyroscopic effect resulting from the four propellers rotation [5,9,[13][14][15]. The third type ideally included the gyroscopic effects resulting from both the rigid body rotation in space and the four propellers' rotation [3,4,8,16,17].…”

Development and Implementation of a Adaptive Fuzzy Control System for a VTOL Vehicle in Hovering Mode

“…Suter et al also studied on image based visual servo control for quadrotors [9]. Dunfied et al created a neural networks controller for a quadrotor [10]. Earl et al used a Kalman filter to estimate the attitude of a quadrotor [11].…”
