稀薄流区的多弹协同编队构型生成策略设计

This paper focuses on the formation flight control problem of multiple-missile in the thin flow zone. In order to satisfy the optimal space configuration constraints and achieve the accurate target location, a cooperative formation strategy is proposed based on the attitude and orbit control technology of the reaction control system (RCS). The cooperative guidance scheme is fulfilled considering all constraints. Then, to achieve the flight attitude tracking and stable controlling for missiles, the attitude control scheme is designed by using the classical proportion integration differentiation (PID) technology. At the same time, the pulse width pulse frequency (PWPF) modulator is used to convert continuous control variables into equivalent nozzle control instructions, which can reduce the engine fuel consumption effectively under the premise of maintaining attitude stability control. The simulation results indicate that the cooperative guidance and control strategy can ensure the attitude stability for missiles in the flight process, and make the space configuration approximate to the foptimum.
