摘要
为克服场面开环控制模式难以应对随机事件的缺陷,提出场面运行闭环控制框架.基于DES(离散事件系统)监控理论,研究A-SMGCS(先进机场场面引导与控制系统)滑行道对头冲突控制,建立了面向滑行道物理布局的扩展受控Petri网模型.利用航空器滑行路径序列得到精简滑行模型,并考虑环路和环路链,给出无对头冲突的充分必要条件,提出了滑行道对头冲突避免控制策略以及相应的控制律决策算法.算例仿真试验表明,本文提出的策略能根据场面状态实时识别对头冲突并实现冲突避免.
A closed loop control approach was proposed to overcome the shortcomings of open loop control that can not tackle stochastic events in airport surface operations.A control strategy for head-on conflict on taxiway in an airport equipped with an A-SMGCS（advanced surface movement guidance and control system） was investigated based on the supervisory control theory of DES（discrete event systems）.A controlled Petri net model for the taxiway layout was established,which maps the set of places to the set of taxiing routes.The model was simplified using the known taxiing routes sequences of aircrafts.The sufficient and necessary conditions to avoid head-on conflict on taxiway were determined with the loops and loop chain being considered.Conflict avoidance strategies and the corresponding algorithm for decision-making were presented.Simulation demonstrated that the proposed strategy could identify and avoid head-on conflict on taxiway in real time by monitoring the surface operations.
