A Missile Guidance Law for Multiple Missiles Attacking Maneuvering Targets Simultaneously

Abstract

The invention discloses a missile guidance law for multiple missiles attacking maneuvering targets simultaneously, aiming at providing missiles with a guidance law whose stable time does not depend on system initial conditions when multiple missiles attack maneuvering targets. In order to achieve fast response and robustness of the system, a non-singular fast terminal sliding mode surface with fixed time convergence is designed. This sliding mode surface has the characteristics of traditional terminal sliding mode fast convergence and non-singularity. Based on the designed sliding mode surface, a guidance law that converges at a fixed time along and perpendicular to the line of sight of the projectile is constructed. The design parameters of the two guidance laws are independent of each other, and the parameters can be matched according to the system performance requirements, and the saturation function is introduced in the guidance law To avoid system chatter, the guidance law has a simple structure and is easy to implement.

Description

technical field

[0001] The invention belongs to the field of automatic coordinated control, and in particular relates to a missile guidance law used for multiple missiles to simultaneously attack a maneuvering 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 development of a...
