摘要
综述了单框架控制力矩陀螺 (SGCMG)系统操纵律研究概况 ,并对现存操纵律的性能进行了评价。通过分析可以知道 ,现存的SGCMG操纵律或在奇异回避性能方面较差 ,或由于计算量较大而使得实时性较差等等 ,从而使其在航天器姿态控制中的应用受到了极大的阻碍。要提高SGCMG系统的操纵性能 ,可在以下三个方面作进一步研究 :零运动的选择方法、操纵律的闭环实现、框架伺服特性的考虑等。
A survey of steering laws for Single Gimbal Control Moment Gyroscope(SGCMG) systems is made.Meanwhile,steering performance of the art is appreciated.Obviously,all the steering laws of the day have poor performance either in singularity avoidance,or in calculation burden of large amount.In order to improve steering performance and apply SGCMGs to spacecraft attitude control better,the following work can be studied further,i.e.,choice of null motion,closed loop realization of steering laws,consideration of gimbal servo characteristics.
