多操纵面战斗机动态控制分配策略研究

Dynamic Control Allocation of Fighter with Multi—effectors

针对多操纵面战斗机飞行控制系统中操纵面控制分配器设计问题,提出了一种动态控制分配策略方案。策略从频率域角度建立虚拟控制量和实际控制量的动态映射,充分利用操纵面的不同带宽,将期望力矩分配到各个操纵面,使各个操纵面协调工作,达到最大控制效能。数字仿真结果表明相对于其他控制分配策略,采用动态控制分配策略的控制分配器在达到控制要求的同时,可以有效地减小座舱过载并使配平阻力最小,取得了良好的控制效果。

The problem of control allocation - distribution of control power among redundant control effectors is mostly solved by static control allocation schemes . Regardless of the methods （optimization based allocation, daisy chain allocation, direct allocation, etc ）, they can be thought of as affecting the distribution of control effect in magnitude among the actuators . A possibility that has been less explored is to affect the distribution of the control effect in the frequency domain, and use the redundancy to make different actuators operate in different parts of the frequency spectrum. Here, a new systematic method for dynamic control allocation is proposed. And it is proved to have outstanding features.
