在研究指令灵敏度的基础上,定义了一种描述控制分配算法响应飞机包线范围内工作状态变化的灵敏度。阐明了控制分配模块的功能,对比研究了两类实时性较好的混合优化控制分配算法:线性混合优化法和二次混合优化法;分别采用单纯型法和有效集法进行求解,结合指令灵敏度和状态灵敏度的定义分析了两类混合优化方法的灵敏度。计算结果表明,在虚拟指令可达范围内状态灵敏度能更好地描述算法的收敛性,而在接近可达极限时指令灵敏度则更好地反映了算法的平稳性。
On the basis of the research of command sensitivity, a sensitivity is described which describes the control assignment algorithm to respond to the change of working status in the area of the aircraft envelope. The functions of the control distribution module are clarified. Two kinds of hybrid optimization control allocation algorithms with good real-time performance are comparatively studied: linear hybrid optimization method and quadratic hybrid optimization method. The simplex method and effective set method are respectively used to solve the problem. Combined with the instruction sensitivity And the definition of state sensitivity analyzes the sensitivity of two kinds of hybrid optimization methods. The calculation results show that the state sensitivity can describe the convergence of the algorithm better in the range of the virtual instruction reachability, while the instruction sensitivity reflects the stability of the algorithm better when the reachable limit is reached.
