摘要
研究了月球探测器转速与控制力矩受限的姿态大角度机动问题。根据时间变尺度思想 ,提出了双回路反馈的姿态大角度机动控制方法。以某型月球控测器为例 ,对该方法进行了仿真验证。结果表明 ,利用该控制方法 ,可使探测器以期望的角速度转动 。
This paper studies the attitude large angle slew problem that rate and control moment of the lunar probe are limited. Based on idea of time scale, an attitude large angle slew control method is presented. Taking aim at the kinematics model of the probe, the expectated angle rate is obtained with the limit of reaction wheels rate saturation. The angle rate tracking controller is designed to track the expectated angle rate, and the attitude large angle slew of the probe is realized.
