摘　　要：以近空间飞行器直/气异构复合控制为应用背景,针对常见复合控制分配方法没有考虑执行机构的异构特性差异,导致实际控制效果难以达到期望效果,以及姿态震荡和RCS能量消耗都较大的技术难题,提出了一种基于整数规划策略的复合控制分配方案。该方法将直/气复合控制分配的RCS力矩实现问题转为一个0-1整数规划问题,能有效解决异构执行机构的控制分配问题。仿真结果表明,该方法能有效降低能量消耗和姿态震荡。This study aims to achieve the heterogeneous direct force/aerodynamic force compound control of near-space vehicles(NSVs).As conventional compound control of NSVs ignores the difference in heterogeneous characteristics of the executive body,the actual control performance cannot fulfill the expectation,and the method faces the problems of significant attitude oscillation and great energy consumption of the reaction control system(RCS).Hence,a compound control allocation method based on 0-1 integer programming is proposed.With this method,the moment realization problem of RCS allocated by direct force/aerodynamic force compound control is changed to a 0-1 integer programming problem.In this way,the control allocation problem of the heterogeneous execution body can be effectively addressed.The simulation indicates that the proposed method can effectively reduce energy consumption and attitude oscillation.
