摘　　要：文章通过分析高超声速飞行器再入段横侧向对象特性,确定动压达到一定条件气动舵面完全参与姿态控制时的滚转控制策略.基于滚转回路结构,理论分析滚转回路性能指标与控制律参数的关系,估计舵系统带宽.结合仿真手段,给出典型状态下的定点计算结果,确定舵系统带宽要求.另外,通过仿真研究,探讨舵系统时间常数、阻尼比和时延对滚转控制品质的影响.The design of roll control is presented under the certain dynamic pressure condition that aero- dynamic rudder is completely used for attitude control, via the analysis of stability and control characteris- tic on reentry of hypersonic vehicle. According to the roll-loop structure, the relationship between roll- loop performance index and control parameters is analyzed, and the rudder bandwidth is estimated. On this basis, the minimum rudder bandwidth in different flight feature points is given. In addition, with the help of the simulation results, the effects of time constants, damping ratio and delay time of the rudder system on the performance of roll control quality are studied.
