超低空掠海拖靶定高飞行控制系统设计与实现

Design and Realization of Height Keeping Control System of Low Level Sea-Skimming Tow Target

航空拖靶作为一种消耗性靶标装备,为了使其成本低廉,其设计中一个突出要求是结构要简单。在某新型航空拖靶气动外形的高稳定性布局设计的基础上,应用直接升力控制的原理,实现对拖靶升降运动的控制。采用了一种卡尔曼互补滤波算法滤除高度信号噪声,在获取高度信号和垂向加速度信号基础上,能够获得高质量的垂向速度信号。设计了基于ARM嵌入式系统的拖靶超低空掠海定高飞行控制系统,进行了原理样机的半实物仿真验证。仿真结果表明,系统响应快、控制精度高,能够准确控制拖靶做超低空掠海定高飞行,达到了设计要求。

The height keeping control system of a tow level sea--skimming tow target is designed based on the pri＋neiple of direct lift control in the development of a new type of aerial tow target. The results of hardware--in--loop simulation of the principle machine show that the control system has a high precision with quick response and can control the target flying with low level sea--skimming height precisely and meets the design requirements.
