Airborne Seeker Application in Three Dimensional Formation Flight of Uavs

This paper deals with the leaderfollower formation control problem while communication constraint in data transmitting is considered. from a practical point of view, we study the case in which unmanned vehicles are subject to the limited sensing, and communication is of a particular interest. a threedimensional formation flight of multiunmanned aerial vehicles with leaderfollower configuration is investigated. we assume that the follower is equipped with an airborne seeker to measure the relative kinematic parameters with respect to the leader. considering practical measurements of the airborne seeker, the kinematics of the leaderfollower system is derived and by employing a cascade loop controller, the relative angle and the relative range are regulated to reach at the desired formation. moreover, by modeling the seeker mechanism, the effect of the seeker dynamics and sensor measurement noise on the performance of the proposed formation control scheme are studied. simulation results verify the effectiveness of the proposed leaderfollower formation control structure
