中文摘要： 大型枢纽机场采用场面雷达进行跑道、滑行道和场面目标活动监视，容易受地杂波、气候影响而不能识别目标，使高密度、大容量机场存在飞机与移动车辆相撞的安全隐患。研发基于自动相关监视的先进的场面引导与控制系统，对于保证机场安全具有重要意义。本课题首次将基于Petri网的离散事件监控理论用于场面活动引导与控制中，提出基于网简化技术的场面活动对象状态反馈监控理论，使得场面活动即被控对象满足所期望的安全行为。并对集中式冲突检测单点失效的不足，提出将场面活动监控系统划分为若干个代理子系统，研究满足控制规范的分散式监控器和协调分散控制器设计算法，提高系统的可靠性。研究滑行道使用规则到状态禁止问题的转换方法，为实现多目标动态滑行/行进路径规划，提出将最优路径规划问题转化为固定端点的最优控制问题，达到从战术层次消解冲突的目的。本课题的研究工作将为今后场面及空中冲突探测与解脱技术研究开辟新的研究方向。

英文摘要： For large airport, surface monitoring radar (SMR) is used to surveilling object movements in runways, taxiways and surface, while SMR can not identify objects by reason of ground clutter and bad weather, which leads to hidden trouble of collision between aircrafts and vehicles in the high density and large capacity airports. Developing advanced surface movements guidance and control system (A-SMGCS) based on automatic dependent surveillance (ADS) technolgoy can guarantee the safety of airports. In this research, discrete event system supervisory control theory based on Petri Nets is first used to developing A-SMGCS, in which transforming traffic rules for runway, taxiway and surface into forbidden state problems method should be researched, and surface mobile objects' state feedback control using Petri Nets reducing method is proposed to ensure surface movements satisfy expected safe behaviors. To avoid single point failure of centralized collision detection system, it is proposed dividing A-AMGCS into several agent-based sub-systems, and researching decentralized and coordinated control algorithm satisfying control criterions, which can imporve reliability of A-SMGCS greatly. To realize multi-objects and dynamic taxi route planning, the taxi route planning problem is transformed into fixed point optimal control problem, which can resolve collision from tactical surface traffic management point of view. In general, the result of this research will break a new path for the future collision detection and resolution in the airport and airspace.
