Problems solved by technology

[0006] 2) The impact of random factors on the system in the missile autonomous formation mission cannot be ignored
Secondly, these random disturbances cannot be ignored in autonomous missile formations, and the more highly dynamic, flat, dense, and large-scale formations, the less likely it is to ignore the impact of the above random factors on the system
Otherwise, if the randomness of the above-mentioned interference is ignored or...

Abstract

The invention discloses a modeling method of a formation stochastic control system for missile autonomous formation with multiplicative noise, and belongs to the technical field of aircraft formationnavigation, guidance and control. The modeling method takes the formation stochastic control system for missile autonomous formation as a research object, and the obtains a stochastic system model forformation control by performing analysis and modeling on the formation stochastic interference and introducing stochastic factors into a formation model. For the control problem of the formation stochastic model for missile autonomous formation, the modeling method uses an estimator to estimate the system state, and uses a stochastic robust analysis and design method (SRAD) to optimize the estimator and controller of the formation stochastic model, so that the parameters of the controller can meet the requirements of stability and performance.

Description

technical field [0001] The invention belongs to the technical field of aircraft formation navigation, guidance and control, and in particular relates to a modeling method for a missile autonomous formation random control system with multiplicative noise. Background technique [0002] The main research content of formation control includes: the mathematical model of formation control, the control strategy and method of formation formation, the collision avoidance and obstacle avoidance of formation, etc. So far, there are many studies on the formation control of low-speed robot formations and UAV formations based on particle models with relatively high control accuracy, while high-speed formation control based on multi-constraint complex models and relatively low control accuracy. There are few researches on the formation control of low flying missile formations; there are more researches on the formation control of loose formations that are friendly to the mission environmen...
