Abstract: The design of roll control is presented under the certain dynamic pressure condition that aerodynamic rudder is completely used for attitude control, via the analysis of stability and control characteristic 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.

Key words: roll control, bandwidth of rudder system
