为实现未来大流量、高密度、小间隔条件下的空中交通管理,提出了一种避免飞行冲突的混杂控制系统结构。首先依据不同飞行状态下的航空器运动学方程建立被控对象模型,依据空中交通管制规则确定了禁止空中交通系统轨迹穿越的冲突超曲面,并通过设计监控器辨识潜在的冲突事件。然后基于管制员可采用的调配手段设计飞行冲突离散控制器,根据离散冲突事件向量确定可行的离散解脱策略,并在允许解脱时间段内且系统超曲面函数值的差分为负的前提下计算连续操纵输入量。案例研究表明,混杂系统理论模型能对潜在冲突进行实时探测和解脱,保证空中交通系统处于可达集的安全子集中。
In order to realize the air traffic management in the future with high flow rate, high density and small interval, a hybrid control system structure to avoid the flight conflict is proposed. Firstly, the controlled object model is established according to the aircraft kinematics equation under different flight conditions. Conflict hypersurfaces that prohibit the air traffic system trajectory from traversing are determined according to the air traffic control rules. The potential conflict events are identified through the design of the monitor. Then, based on the deployment method available to the controllers, a discrete controller for flight conflict is designed. Based on the discrete conflict event vectors, a feasible discrete strategy is determined and then the continuous discrete flight strategy is calculated under the condition of allowable release time and the difference of the hypersurface function value is negative Manipulate input. Case studies show that the hybrid system theory model can detect and release potential conflicts in real time and ensure that the air traffic system is in a reachable set of security subsets.
