| 中文摘要 |
| 作为应用在航天器上的惯性执行机构, 单框架控制力矩陀螺(SGCMG)系统框架角空间的轨迹跟踪性能对航天器姿态控制(或稳定)精度有着极大的影响. 为提高SGCMG系统框架角轨迹跟踪性能, 本文在轨迹跟踪控制中, 采用了“PD +自适应补偿”的控制器结构. 通过分析可以发现, 此种控制器不但可使轨迹跟踪误差收敛至零, 实现有限时间跟踪控制, 而且可使轨迹跟踪误差每一分量的绝对值指数收敛. 对应用在航天器上的金字塔形4-SGCMG系统框架角空间轨迹跟踪控制的仿真结果表明, 上述控制算法是可行的. |
| 英文摘要 |
| As inertial actuators mounted on the spacecraft, single gimbal control moment gyroscope(SGCMG) systems can affect the attitude control accuracy to a great extent. In order to improve the trajectory tracking performance in gimbal angle space for SGCMG systems, an adaptive compensation controller is adopted, which has three terms, i.e., proportional, differential, and adaptive compensation ones. This controller not only can realize finite time tracking control in gimbal angle space, but also can make the tracking error converge to zero exponentially. Simulation results of a certain pyramid-type-4-SGCMG system indicate that the control algorithm presented above is feasible. |
