摘要
为避免大型高密度机场航空器之间可能发生的冲突,提出了一种基于混杂系统结构的滑行引导方案.建立了航空器滑行连续动力学模型和航空器在滑行道直线段、交叉口运行的离散事件动态系统模型,通过场面运行观测器建立了连续状态到离散状态的映射.采用禁止状态线性不等式约束和禁止状态逻辑互斥约束,描述场面运行模型应遵循的控制规范,并给出满足控制规范的离散控制器设计方法.最后建立了运行模型中可控变迁的使能状态到场面冲突控制策略的映射.通过助航灯光沙盘控制系统的验证表明,该滑行引导方法能及时对可能冲突的航空器采取恰当的控制策略,并实时生成航空器滑行操纵指令,能有效避免航空器滑行冲突.
To avoid contliction troubles between aircrafts at high density airports, an aircraft taxiing guidance framework based on hybrid system is proposed. Firstly, an aircraft taxiing dynamic model in continuous space and discrete event dynamic system models for the taxiing operation on straightaway and intersection are built, and a surface operation observer that maps the continuous dynamic state into discrete observation is proposed. Secondly, the forbidden state avoidance-based regulations described by linear inequality constraints and logical mutex constraints are introduced to express surface traffic control rules, and the discrete controller design method are proposed. Finally, the mapping from the enabling state of controllable transition in the straightaway and intersection operation models to control strategies is built. The validation by control system of an airfield lighting sand table shows that the taxiing guidance method can issue feasible control strategies in time and generate taxi manoeuvring instructions for aircrafts to avoid potential taxiing conflicts effectively.
