Two-stage cooperative rendezvous method for winged aircraft in initial guidance phase
To solve the problem of cooperative rendezvous of multiple winged aircraft flying across large airspace in the initial guidance phase,the cooperative rendezvous problem is transformed into the problem of time and position coordination between the initial deployment point and the formation cooperative flight area.The cooperative rendezvous process is divided into two stages.In the first stage,there is no information interaction between the aircraft.A cooperative rendezvous method with rendezvous angle constraints is designed to specify a common rendezvous time and angle for each aircraft.Fuzzy logic is used to realize the reasonable allocation of trajectory control and speed control.Then it turns to the second stage of cooperative rendezvous flight after establishing a reliable communication topology and meeting the terminal's relaxed judgment conditions.In the second stage,a cooperative rendezvous method based on formation tracking control is designed for the follower aircraft,by using the communication topology interaction information built between them.The stability of the closed-loop system is proved by Lyapunov theory.Simulation example verifies the effectiveness of the proposed method.
