多枚倾斜转弯导弹的滚转通道之分布式有限时间姿态协调控制

对多枚倾斜转弯(BTT)导弹设计滚转通道自动驾驶仪时,基于分布式协调控制理论,本文提出了一类分布式有限时间姿态协调控制器.由于BTT导弹的气动参数变化强烈、机动要求高,要求控制器响应速度高,抗干扰能力强.本文基于有限时间控制技术,并结合多智能体系统的协调控制理论,对多枚BTT导弹滚转通道提出了一种分布式有限时间姿态协调控制律.在该控制律作用下,所有的BTT导弹通过相互协调,其滚转角可以在有限时间内达到一致并为给定的参考指令信号.仿真结果表明了该方法的有效性.

Distributed finite-time attitude cooperative control for roll channels of multiple bank-to-turn missiles

Since bank-to-turn (BTT) missiles are with time-varying aerodynamic parameters and are required to carry out large angle maneuver, etc., the attitude controller must provide a fast response and strong disturbance-rejection performances. To this end, based on the technique of finite-time control and the theory of cooperative control of multi-agent systems, a distributed finite-time attitude cooperative control law is proposed. According to the proposed control law, the roll angles of all BTT missiles can achieve a state-consensus in a finite time, which is the desired roll angle. Simulation results are given to demonstrate the effectiveness of the proposed method.
