摘　　要：针对多操纵面飞机控制分配方案缺乏统一的评价准则问题,提出基于蒙特卡洛的控制分配鲁棒性评估方法。首先,基于典型的飞机控制分配模型,借助于飞机飞行品质评估的思想,分析控制分配方法鲁棒性评估的流程;考虑舵面效率的不确定性范围,根据鲁棒性要求的精度和置信度确定仿真参数,基于蒙特卡洛方法建立了过驱系统分配方法鲁棒性的评估函数;最后,基于鲁棒性评估方法,实现伪逆法、串接链法和面搜索法三种控制分配方案的鲁棒性能评估。仿真结果验证了该方法的有效性,能够为控制分配鲁棒性评估提供理论支撑和技术手段。The present control allocation scheme lack of unified evaluation criterion for aircraft with multiple control surfaces,a general robustness evaluation method of control allocation was proposed based on Monte Carlo method.Firstly,based on the typical aircraft control allocation model and the idea of aircraft flight quality evaluation,the process of robustness evaluation of control allocation method was analyzed.Secondly,considering the uncertainty range of surface efficiency,the simulation parameters were obtained according to the accuracy and confidence required by robustness,and the robustness evaluation function of over drive system allocation method was established based on Monte Carlo method.Finally,the robustness evaluation of three control allocation methods:pseudo inverse,daisy chain and surface search were realized,which verified the effectiveness of the proposed method,and provided theoretical support and technical means for the robustness evaluation of control allocation.
