The purpose of control allocation is to choose a configuration of the control effectors to meet a specified objective. Mathematically, the attainable moment subset (AMS) produced by control surfaces can be expressed as a mapping of the subset of constrained controls into the moment space. The determination of the AMS is very important to the solving of the allocation problem. For the two-dimensional allocation problem, a numerical algorithm is proposed to solve the AMS on-line. For the complex three-dimensional allocation problem, by analyzing its allocation characteristic, some comprehensive mathematic analyses are given to solve the three-dimension AMS. After that, an improved direct allocation algorithm based on the determination of AMS is proposed. Compared to the common direct allocation algorithm at fast speed, the improved algorithm can find the right facet which intersects with the desired moment and improves the real time performance of the allocation system well.
