弹道式飞行器再入时，常常要求在规定高度上发出开伞信号，目前用的过载延时控制方法误差太大。本文以飞行器轴向视速度及其积分为控制信号，用共扼方程法设计了一种惯性高度控制方案。计算结果表明，该方案的控制误差小于１００ｍ。
Ballistic aircraft reentry, often require the issue of open parachute signal at the specified height, the current overload delay control method error is too large. In this paper, the axial velocity of the aircraft and its integral are used as the control signals, and a control scheme of inertia height is designed by conjugate equation method. The calculation results show that the control error of this scheme is less than 100m.
