轨迹发生器设计与仿真

轨迹发生器在惯性导航技术研究过程中是非常重要的，本文介绍了轨迹发生器软件包设计的整体思路，详细推导了轨迹方程，描述了外部信息控制下的位置、速度、姿态、比力以及载体绝对角速度的变化规律，分析了载机在直线飞行、滚转摇摆、转弯机动、正弦机动四种飞行轨迹的控制规律，完成了相应的控制方程的设计，最后对载机在对称轴滚转摇摆飞行状态时轨迹发生器进行了仿真。仿真结果表明该轨迹发生器的设计是正确的，符合载机飞行的各种实际状态。

Abstract: The tracking producer software package is very important in the inertial navigation research period. In this paper, the whole design thought of tracking producer software package is introduced, and track equation and its control equation are detailed. Then the paper describes the regulation of plane body’s position, velocity, attitude, force and absolute angle velocity. In addition, control regulation is analyzed which is under the condition of straightaway, rolling, turning, sinusoidal flying state. Finally, it is simulated what tracking producer exports while the plane body flies and rolls along its symmetrical axis. The simulation results show that the design of the tracking producer package is correct, which is true of all kinds of the plane body’s actual states.
