摘要

为了使红外成像导引头能够稳定、精确地跟踪目标

必须保证目标视线始终位于侧窗允许的视场范围之内.本文以美国THAAD拦截弹动能杀伤器导引头为研究对象

建立了目标视线角与弹体前部的动能杀伤器(kinetic kill vehicle

KKV)弹体姿态角之间的联系

根据测得的目标视线的变化及时调整KKV弹体姿态.为了进一步拓展研究思路

使控制量为连续形式的控制方法也能够用于KKV弹体的姿态控制

基于时标分离原理设计了控制器

并利用脉宽脉频调制将连续控制变量转换为离散常值输出力矩.仿真试验表明

当导引头处于跟踪阶段时

所设计的控制律能够使滚转角速度保持为0

滚转角保持不变

而俯仰角、偏航角准确跟踪指令值

整个过程中实现了姿态角的精确跟踪.

Abstract

For achieving stable and accurate target tracking

the line-of-sight(LOS)has to be within the allowable range of the IR seeker field-of-view(FOV). In this paper

the THAAD kinetic kill vehicle(KKV)is studied

and a new side window orientation scheme is put forward to adjust the KKV attitude angles according to the LOS angles. The attitude and divert thrusters are activated in pulse mode. To apply the controller in continuous form to attitude control

the pulse-width pulse-frequency(PWPF)modulation is introduced to control the thrusters firing. The time-scale separation technique is chosen to synthesize the control law during side window detection maneuver

and the PWPF modulator is used to modulate the continuous control signal to discrete one. Simulation result shows that when the seeker works in track mode

the proposed control scheme keeps the roll rate as zero

and the roll angle unchanged

while the pitch and yaw angles track the attitude command accurately during the whole side window orientation process.
