针对多操纵面受限控制分配问题,提出了一种新的直接分配算法———平行边搜索法。该算法通过坐标变换和投影,将n(n≥3)维目标的受限控制分配问题转化为若干2维目标的受限控制分配问题,在大大降低了计算复杂度的同时,也改进了其它直接分配算法只能分配3维目标的缺陷。此外,新算法还放宽了控制效率矩阵中任意n列向量都线性无关的条件,并且对于所有情况都能得到最优解。经仿真验证,新算法与其它控制分配算法相比,具有更小的计算复杂度和分配误差,能够满足实时性和精确性的要求。
Aiming at the restricted control assignment of multiple control surfaces, a new direct assignment algorithm (parallel edge search method) is proposed. The algorithm transforms the restricted control assignment of n (n≥3) -dimensional objects into the restricted control assignment problem of some two-dimensional objects through coordinate transformation and projection, which not only greatly reduces the computational complexity but also improves the other Direct allocation algorithms can only allocate 3-D target defects. In addition, the new algorithm relaxes the linearly independent condition for any n columns of vectors in the control efficiency matrix, and yields the optimal solution for all cases. The simulation results show that the new algorithm has less computational complexity and distribution error than other control allocation algorithms and meets the requirements of real-time and accuracy.
