Multi-missile cooperative guidance law design method for maneuvering target and time delay communication

Abstract

The invention discloses a multi-missile cooperative guidance law design method for a maneuvering target and time delay communication. The method includes the steps of, for the maneuvering target whoseacceleration is unknown, establishing a kinematic model of the relative positional relationship between missiles and the target in a three-dimensional space; in a pitch direction and an offset direction, establishing a guidance law by using discontinuous control so that the components, in the two directions, of the relative velocities of the missiles and the target can converge to zero in a limited time and it can be ensured that the missiles can finally hit the target; in the direction of the line of sight, establishing a distributed guidance law by using a communication network between themissiles, a coherence protocol and the discontinuous control so that when the communication network contains time lag, the components of the distance and speed of each missile relative to the target in the direction of the line of sight can be consistent. By using a continuous method and a parameter adaptive method, the guidance law is improved in the three directions, so that control input abruptand buffeting phenomena are reduced while the precision requirement is met.

Description

technical field [0001] The invention relates to a distributed guidance law design method for controlling multiple missiles in coordinated operations in three-dimensional space, in particular to a multi-missile coordinated guidance law design method for maneuvering targets and time-delay communication. Background technique [0002] With the extensive application of new advanced weapons, the air defense early warning mechanism is becoming more and more mature, and the traditional single combat missile has a high probability of being intercepted by the enemy's air defense system, making it difficult to effectively strike the target; while a saturation attack relying on multiple missiles will lead to The cost of attack is too high, reducing the profit of attack. In recent years, communication technology has developed rapidly. Using network information interaction, multi-missiles can achieve coordinated operations and simultaneous strikes on targets, which greatly makes up for th...

AI Technical Summary

Problems solved by technology

Communication time lag may lead to obvious errors in the missile's hit time, reducing the effect of coordinated attacks, so this factor cannot be ignored

For the research on the three-dimensional cooperative guidance law of maneuvering targets under the communication delay, there is no relevant literature
