Real-Time Adjustment Strategy of Aircraft Taxiing Routes for A-SMGCS
摘要
Abstract
Adjustment of airport taxiing routes in operation phase of aircrafts needs a large amount of calculation,which makes it difficult to meet the real-time requirements for A-SMGCS (advanced surface movement guidance and control system). In order to resolve this problem,a colored taxiway-oriented Petri net model was built and a method of aircraft taxiing routes adjustment was proposed. The method abstracted taxiing routes to the visiting priorities of aircrafts on a road section. The delayed aircrafts were punished by decreasing the priorities to visit the road section. To change priorities of aircrafts might lead to two kinds of conflicts:head-on conflicts and circular wait conflicts. Sufficient condition and priority change strategy of aircrafts conflict-free taxiing were proposed to solve those conflicts by analyzing the special structural characteristics of cycle chains and circuits of the colored taxiway-oriented Petri net model. An application example shows that the proposed method can avoid conflicts in aircrafts taxiing routes adjustment. The computation time is less than 10 s,which meets the planning time requirements of A-SMGCS. The control rules are simple,effective and suitable for real-time control.关键词
