Research On Autonomous Flight Control And Attacking Of Uninhabited Combat Aerial Vehicle

This thesis mainly deals with the autonomous flight control system, flight control law and autonomous attacking of UCAV (Uninhabited Combat Aerial Vehicle).Firstly, based on the characteristic of flight control of UCAV, put forward a Hybird Control system with Mutil-Agent and hierarchical control. Give the detailed design of autonomous flight control system of UCAV in the situation of attacking process. It is the base of the following chapters. After introducing the main agents, bring forward the algorithm of path planning agent.Secondly, take more detail research on flight control law. After introducing the UCAV model and TLC (Trajectory Linearization Control), put forward a TLC controller for UCAV. Considering the system model error and outside disturbance will degrade the performance of current TLC controller, a fuzzy wavelet neural network trajectory linearization control method is proposed and corresponding controller is designed. Simulation results demonstrate the feasibility of the approach.Thirdly, a discussion is devoted to study the autonomous attacking of UCAV on combat zone. Corresponding to the decision Agent and maneuver Agent. The study includs air combat situation, multi-aircraft cooperative multi-target attack model, evaluation function, HPSO(Heuristic Particle Swarm Optimization) algorithm and guidance law.Achieved the basic function of the mission plan system of autonomous attacking.Finally, based on Windows platform, the three dimension visual simulation of air-to-air attack is developed using MultiGen Creator and Vega software, which shows the entire process of missile attacking plane vividly.
