引入自动驾驶仪时空中交通防撞系统的仿真

空中交通防撞的主要功能是对本机和入侵目标机位置的预测以及在预测后对冲突的处理。在防撞过程中,入侵飞机的轨迹突然发生比较大的机动,则原有的防撞策略失效。2009年欧洲航空安全局认证通过了自动驾驶仪在避撞时与防撞系统耦合的方法,使问题得到了一定的解决。对避撞系统加入自动驾驶仪的方法进行了研究建模,并且对解决的情况进行了仿真,为民航空中交通避撞提出了一种新的思路。

Simulation of Traffic Collision Avoidance System Introduced in Auto-Pilot

The prime function of Traffic Collision Avoidance System(TCAS) is to forecast the position of both aircrafts in conflictthus the potential collision can be handled properly.During the collision avoidance processmaneuver of the intrude aircraft might happenand the original plan would be invalid.In the year of 2009EASA certified a method that TCAS can be integrated with auto-pilot while in the process of collision avoidance.Therefore the problem can be solved to some extent.In this paperthe method of adding the auto-pilot into the Collision Avoidance System was used.Mathematical models were established and the final situation was simulated by using Matlab.It would provide a new idea for TCAS in civil aviation.
