串接链分配法将包含推力矢量操纵面在内的所有舵面按照优先级分为若干组,对于期望的转矩指令,如果优先级高的一组无法有效分配则启用次级操纵面,如何使基于串接链设计的分配系统根据期望转矩的大小对各组舵面进行自动调用与分配是一个难点。文章对串接链的可达转矩集进行了求解,将各组舵面所能有效分配的最大转矩值作为分配系统实施舵面调用与管理的阈值。串接链的转矩可达集是复杂的非凸几何体,解析方法无法求解,文中通过对分配系统AMS的几何构造分析,提出了一种基于微元的串接链可达集数值求解算法。将串接链的分配效率作为适应度函数,通过遗传算法选择具有最大可达集的广义逆阵,提高了算法的分配效率。
The tandem chain distribution method divides all rudder surfaces including the thrust vector control surfaces into several groups according to the priority, and for the desired torque command, the secondary control surface is enabled if the group with the highest priority can not be effectively allocated. It is a difficult point to make the distribution system based on tandem chain design automatically call and distribute each group’s rudder according to the expected torque. In this paper, the set of reachable torque of tandem chain is solved, and the maximum torque that can be effectively distributed by each group of rudder is taken as the threshold of the system call and management. The torque reachable set of tandem chain is a complex non-convex geometry, which can not be solved by the analytical method. Based on the geometric structure analysis of AMS, a tandem chain reachable set-based numerical solution algorithm is proposed. The distribution efficiency of the tandem chain is taken as fitness function, and the generalized inverse matrix with the maximum reachable set is selected by genetic algorithm to improve the allocation efficiency of the algorithm.
