Abstract


UAVs play an irreplaceable role in the current war , the key issues of the paper focuses on UAV autonomous flight control and management decision-making techniques design and simulation . The first part of the study the the UAVs autonomous flight management architecture based on open- layered hierarchical structure . The main components of the structure , to study the structure and function of the key modules . The second part of the key modules of the design of the structure design . First designed route planning module and flight path tracking module . For the Route Planning actual need , route planning is divided into two-dimensional route planning and the 2D route point between 3D route planning ; proposed the three-dimensional dynamic weights LPA * route planning method of two-dimensional route routes between planning, real-time re- planning of the sudden appearance of a new threat , the use of three-dimensional D * Lite . Followed by slow modes of the full nonlinear characteristics , design a the track angle tracking instruction flight controller . Again UAV autonomous control of a key technology - autonomous take-off and landing control technology , research , and roll the UAV during takeoff three , two roll and liftoff process away from the land , the longitudinal control law design ; given high system of UAV landing process design , the decline in the beam guidance system , auto- leveled system and lateral beam guidance systems , and simulation . Finally , mission planning and scheduling of UAV flight management task management system . Several sub- tasks will complete the mission by the decomposition of Petri nets , event trigger management and scheduling , Stateflow complex logic to determine the UAV to achieve a friendly interface GUI . The third part of the study on the Windows platform based on the virtual simulation software MultiGen Creator, Vega and VC UAV flight three-dimensional view of the whole process of simulation , a vivid demonstration of take-off , flight and landing .
