A Guidance Law Based on Proportional Guidance Law for Multiple Missiles to Simultaneously Attack Static Targets

Abstract

The invention discloses a proportional guidance law based guidance law for multiple missiles attacking a static target at the same time. When n missiles attack the same static target at the same time, the r of the ith missile is obtained. i , V i and φ i ; and then obtain the consistency deviation ξ of the remaining flight time of n missiles t，i . Then judge the consistency deviation ξ t，i = 0 is true, if true, maintain the current flight status of each missile; if not, change the current consistency deviation ξ t，i input into the guidance law with fixed time convergence to obtain the tangential control input a of the multi-missile system n，i and normal control input a t，i ;Establish the missile dynamics model, and obtain the r at the next moment through the missile dynamics model i , V i and φ i , return to the initial. By adding additional items, the present invention avoids the fact that the angle between the flight direction of the missile and the line of sight of the missile is 0 before the multi-missile system completes the state consistency, so that the system convergence completion time tends to be infinite.

Description

technical field [0001] The invention belongs to the field of automatic cooperative control, and in particular relates to a proportional guidance law-based guidance law for multiple missiles to simultaneously attack a static target. Background technique [0002] With the development of military technology, more and more important targets are equipped with anti-missile defense systems such as short-range weapon systems to improve defense capabilities. Due to the existence of the defense system, for the traditional single missile attack strategy, the defense system is easy to intercept the attacker's missile, which will seriously affect the success rate and reliability of the target attack. Therefore, in order to break through the defense system, it is necessary to develop missiles with high static performance, so as to improve the success rate of attacking the target. However, the cost and technical requirements of such high-static missiles are very high, which hinders the de...
