Neural network output feedback control of a quadrotor UAV

Neural Network Control and Wireless Sensor Network-based Localization of Quadrotor UAV Formations

“…is the general form of a skew symmetric matrix defined as in (Dierks & Jagannathan, 2008 , and this property is commonly referred to as the skew symmetric property (Lewis et al, 1999). The matrix…”

“…Consider a quadrotor UAV with six DOF defined in the inertial coordinate frame , E , and the dynamics of the UAV in the body fixed frame can be written as (Dierks & Jagannathan, 2008) …”

“…In recent years, quadrotor helicopters have become a popular unmanned aerial vehicle (UAV) platform, and their control has been undertaken by many researchers (Dierks & Jagannathan, 2008). However, a team of UAV's working together is often more effective than a single UAV in scenarios like surveillance, search and rescue, and perimeter security.…”

Actuator Fault Estimation and Reconfiguration Control for the Quad-Rotor Helicopter

“…Meanwhile, the system behaviour can deteriorate when actuator, sensor or plant faults take place. Many control approaches have been investigated for the quad-rotor helicopter, such as backstepping control [6], sliding mode control [7], LQ control [8] and neural network control [9], to solve these problems.…”

Fault Tolerant Flight Control Techniques with Application to a Quadrotor UAV Testbed

“…Some theoretical works consider the problems of control (Dierks & Jagannathan, 2008), formation flight (Dierks & Jagannathan, 2009) and fault diagnosis (Nguyen et al, 2009;Rafaralahy et al, 2008) of the quadrotor UAV. However, few research laboratories are carrying out advanced theoretical and experimental works on the system.…”
