摘　　要：现有基于数学规划的操纵面组合分配方法往往忽略操纵面之间物理区别、同时调用所有控制面参与各阶段分配求解,这种做法极不利于算法的工程应用和系统的可靠性。提出了一种基于转矩可达集设计的操纵面组合分配方法,该方法首先计算出各个基控制组的转矩可达集,在此基础上综合分析各个基控制组转矩可达集的构造特点,结合操纵面的气动特性、雷达反射特性、最少推力矢量模式等工程要求,确立一组主控舵面,以使现有常规布局飞机的控制律设计方法和经验得以沿用。而当主控舵面不能满足机动飞行对于可用力矩的需求时,启用辅助操纵面及推力矢量操纵面,辅助操纵面的管理按照舵面偏转对于雷达反射的优先级进行。仿真验证表明:文中提出的方法避免了数学规划法各模态切换带来的复杂问题,按照三轴可用力矩调度管理辅助操纵面、推力矢量操纵面的方法有效可行,能够实现合理的操纵面分配设计。When control allocation method based mathematical programming is used to solve the multi-objective al- location problem, it is needed to establish the allocation objectives of the various phases of flight of the aircraft, and then to use linear programming or quadratic programming method for solving. Although the method can get an opti- mal solution, it neglects the physical differences among the surfaces and dispatches all the control surfaces at the same time, which is not beneficial to the algorithm＇s engineering applications and to system reliability. Especially the algorithm requires automatic mode switch which greatly increases the complexity of control system design. In or- der to solve the problem, an allocation method based on attainable moment subset is proposed. The method first cal- culates the attainable moment subset （AMS） of different effector groups and then chooses a group as the master control surfaces according to its AMS structure characteristic together with its radar reflectivity characteristics and resistance characteristics. So Conventional layout aircraft control law design methods and experience can still be used. When the master control surfaces can not meet the demand for the available torque, auxiliary control surfaces and thrust vector control surfaces will be dispatched ; and the management of the auxiliary control surfaces is in ac- cordance with the priority of the radar reflectivity. The simulation results and their analysis show preliminarily that ： （ 1 ） the proposed method avoids the faults of the allocation methods based on mathematical programming; （2） the way of managing the auxiliary control surfaces and thrust vector control surfaces by available three-axis torques is feasible and a reasonable control allocation design is achieved.
