In this brief, a novel distributed cascade robust feedback control approach is proposed for formation and reconfiguration control of a team of vertical takeoff and landing (VTOL) unmanned air vehicles (UAVs). This approach is based on dynamic communication network. It guarantees intervehicle collision avoidance and considers dynamic constraints of UAVs. In the outer loop of the cascade formation control,...
The modeling of yaw dynamics of a UAV helicopter is focused on together with its control system design. From the flight tests on our actual UAV helicopter, it has been found that the yaw dynamical model for the UAV helicopter proposed in the literatures is very rough and inaccurate, which might cause the helicopter to shake severely in certain flight conditions. A complete examination is carried out...
