飞行仿真中机动指令跟踪器的设计

计算机自动飞行仿真中,由基于飞机质点动力学模型的机动指令生成器生成三自由度控制指令;为了将指令运用于控制飞机六自由度全量模型,从而较好地实现指令控制飞行,需设计机动指令跟踪器。对机动指令跟踪器的设计原理进行了分析;并采用经典的根轨迹法对跟踪器进行了设计。仿真结果表明,该方法设计的指令跟踪器,对于航路飞行仿真可以获得良好的控制效果。

Design of maneuvering command tracker in flight simulation

In automatic flight simulation,the maneuvering command generator based on dynamics model of aircraft mass points can generate 3 Degree-of-Freedom(3-DOF) commands.In order to apply these commands in the 6-DOF aircraft model for realizing better command-controlled flight,a maneuvering command tracker was designed.The principle of the command tracker is analyzed.Then the classical root-locus method was used in the design of the tracker.The simulation results demonstrated that the designed command tracker can well accomplish the path-flight simulation.
