摘要: 基针对现代飞机直接控制分配方法中可达集优化分配的计算复杂度大,难以满足控制实时性要求的问题,提出亚可达集概念,并根据此概念提出了一种基于亚可达集的直接控制分配方法,该方法可得到与可达集相同的控制效果,但计算复杂度低,运算实时性好.仿真结果表明,与可达集方法相比,搜索速度提高了60%,验证了本方法的有效性.另外,本方法也可用于其他多变量控制分配问题的求解.

Abstract: The direct allocation method for modern tactical aircraft is too complicated to meet the real-time requirements.This paper gives the concept of hypo-attainable moment set (HAMS) and then proposes a new direct control allocation scheme based on HAMS to solving the difficulty of direct allocation method.We prove that the new method in HAMS can get the same result as the direct control allocation method in attainable moment set.But the computational complexity is reduced greatly.Simulation shows that the searching speed is increased by 60%,this verifies the effectiveness of the new method.In addition,this method can also be used for other multi-variable control allocation problem.

Key words: flight control, multi-controls, control allocation, AMS(Attainable Moment Set)
