Research on Integrated Guidance and Control for Cooperative Distributed Multiple Flying Objects

Abstract

In this study, aiming at the problem of cooperative target pursuit by multiple flying objects, a cooperative control strategy for distributed multiple flying objects based on integrated guidance and control (IGC) is proposed. First, based on the pitch channel of the flying objects, the leader IGC model of the flying objects is established. The extended state observer (ESO) is designed to estimate the unknown disturbances in the model, and the self-adaptive dynamic surface sliding mode control law is applied to design the leader controller. Further, the distributed network mode based on the leader-follower relationship is applied to design the cooperative control strategy of multiple flying objects to obtain the flying objects' velocity in two directions of the pitch channel, which is transformed into the total velocity of the flying objects and trajectory inclination angle order through kinematics. Finally, the ESO and the controller of the follower flying object that is designed by dynamic surface sliding mode control are applied. The simulation results of two different communication topologies verify the effectiveness of the designed distributed cooperative IGC algorithm for multiple flying objects.
