摘要: |
载人飞船在逃逸飞行过程中,需要对其姿态作较大幅度的调整,调整幅度可达 0°~180°,飞船姿态的调整可以通过控制俯仰通道来完成。由于飞船姿态运动的三个通道一般是相互交连的,因此,在作姿态大幅度调整的过程中,还需要对其它两个通道进行姿态稳定。本文设计的一种相平面开关曲线和相应的姿态控制律,既可以用于飞船作大姿态调整,又可以用于姿态稳定。数字仿真结果表明,只要合理选择开关控制曲线的有关参数,可使姿态控制精度满足设计要求。 |

Abstract: |
Large attitude manoeuvring the amplitude of which ranges from 0°to 180°it is necessary to carried out. The pitch channel can be used in the process of manoeuvre,and the other two are required for attitude stabilization,because all three channels are interreactive in attitude motion generally. In this paper a phase-plan on-off curve and corresponding attitude control law are designed and used in both attitude maneouvre and attitude stabilization. The resu1ts of mathematical simulation shows that the accuracies of attitude control meet the design requirement as long as the parameters of attitude control curve are rationally chosen. |
