Multi-missile cooperative guidance method and system under time-varying delay condition

Abstract

The invention discloses a multi-missile cooperative guidance method and system under a time-varying delay condition. The multi-missile cooperative guidance method under the time-varying delay condition comprises the steps that missile-target motion information is acquired; a missile-target relative motion equation is constructed according to the missile-target motion information; the missile-target relative motion equation is processed by adopting a feedback linearization method to obtain a multi-missile system linear model; and based on a consistency principle, a first normal overload required by the missile and a second normal overload required by the missile are determined according to the multi-missile system linear model, the communication topology function, the communication delay and the missile-target motion information; and the first normal overload and the second normal overload control a plurality of missiles to attack the attack target. Under the condition that time delay exists, the requirement for missile-borne detection equipment can be lowered, and the autonomous performance of the system is improved.

Description

technical field [0001] The invention relates to the field of missile guidance and control, in particular to a multi-missile cooperative guidance method and system under time-varying delay conditions. Background technique [0002] Coordinated guidance of multiple missiles is a hot issue in the field of guidance and control in recent years. Its time-consistent saturation attack on stationary targets or low-speed targets can effectively target enemy radar detection, thereby improving damage capabilities. [0003] There are mainly two types of existing multi-bomb coordination methods. One is to estimate the remaining attack time of missiles. At present, there are several research results on time estimation methods. Among them, the proportional guidance method is used, which leads to the classic time estimation formula. The modulo control method gives the time estimation method and so on. The other is to designate the attack time for coordinated strikes. Each missile calculates...
