自主攻击型无人机的导引技术研究

Research to the Navigation Control of a UAV

针对无人机执行攻击任务前的攻击导引问题,从导引信息的获取、导引控制策略和导引控制律三个方面进行分析。选取光电平台为侦察设备,并具体分析在此侦察设备下导引信息的获取途径。在无人机控制过程中分析比较了两种导引控制策略,指出适合自主控制的导引控制策略并加以改进。在导引控制律方面,对目前广泛使用的比例导引律进行研究,且根据导引律的指令需求在无人机模型上实现了过载控制。

Considering the guide method of a UAV when it takes an attacking mission, there should be an attack navigation at the beginning stage of the attack mission, the key point of this ,stage includes three parts, to acquire the navigation intelligence, to make the navigation strategy, and according to a reasonable navigation strategy to select the appropriate navigation law. For the first part, choosing the photoelectric platform as scout equipment, then basing on this＇equipment analyzes the method to gain enough navigation intelligence. As for the second part, in purpose of making the UAV more self-determination, comparing two control strategies, and giving a reasonable suggestion to improve one strategy. In the last part, an analysis of the proportion guidance law which was widely used is shown, combined the guidance law and the control of UAV decides the control signal-the overload, and shows a simulation to prove it.
