使用比例导引规律的寻的导弹具有检测导引规律所需的视线转率的目标跟踪器.这种目标跟踪器存在两类模型不确定性,它们都将降低导弹导引系统的性能.本文利用波波夫超稳定性理论来分析具有目标跟踪器模型不确定性的导引系统的稳定性.给出了导弹导引系统稳定性同目标跟踪器模型不确定性之间的关系.而且,定义了超稳定最小距离,还给出了超稳定最小距离同目标跟踪器模型不确定性之间的关系.
The guided missiles that use the proportional guidance law have a target tracker to detect the line-of-sight conversion rate required by the guidance law.There are two types of model uncertainties in this target tracker that will reduce the performance of the missile guidance system. The stability of the guidance system with the uncertainty of the target tracker model is analyzed by using the Popov super stability theory and the relationship between the stability of the missile guidance system and the uncertainty of the target tracker model is given.Moreover, The ultrastable minimum distance is defined, and the relationship between the ultrastable minimum distance and the uncertainty of the target tracker model is also given.
