自主近距空战中机动动作库及其综合控制系统

Maneuver Library and Integrated Control System for Autonomous Close-in Air Combat

针对自主近距空战中机动动作库的设计,采用定性与定量结合的方法对机动动作进行描述,以准确体现机动动作的几何形态和战术意义,构成含描述参数的机动动作库。对于机动动作的控制,提出了按照任务控制-运动学控制-动力学控制-被控对象划分的综合控制系统多层递阶结构。其中,机动动作控制器针对每种机动动作分别设计指令生成器,生成气流角和速率指令;气流角控制器采用含指令滤波的backstepping方法进行控制律设计。以半滚倒转和高速摇摇为例进行仿真验证,仿真结果表明,机动动作的描述参数能准确体现其几何形态和战术意义,并通过综合控制系统实现有效控制。

A maneuver library including describing parameters for autonomous close-in air combat is designed. The tactical maneuvers are described in both qualitative manner and quantitative manner for reflecting their geometric forms and tactical meanings. For the control of maneuvers, a multi-hierarchical structure for integrated control system is proposed, which includes assignment management, kinematics control, dynamics control and plant respectively. Maneuvering command generator for each type of tactical maneuvers is designed for generating airstream angle command and velocity command. The control law of airstream angles is designed by backstepping method with command filter. The simulation results of vertical break and high Yo-Yo indicate that, the describing parameters of maneuvers can show the geometric form and tactical meaning exactly, and the integrated control system can achieve the autonomous control of maneuvers.
