摘要
三轴稳定零动量控制方案在卫星姿控系统中被普遍采用,限于卫星寿命和能源补给等,其主要通过调节飞轮转速,进行飞轮与卫星星体之间角动量交换来实现卫星姿态转角控制。本文针对三轴稳定零动量卫星的特点,设计了利用三正一斜装的四动量轮系统进行卫星角动量控制的算法。通过四动量轮系统控制算法,既完成了卫星角动量和姿态的控制,还实现了控制系统的自备份,提高了系统的可靠性,具有重要的工程实践指导意义。
Three-axis stability zero-momentum control strategy was adopted widely in satellite attitude control system. Due to the limit of satellite lifetime and energy supply,angular momentum exchange was the main control method. Paper designed a satellite angular momentum control strategy utilizing three vertical and one inclined fixed momentum wheels. By using four momentum wheel system control algorithm,the satellite angular momentum and attitude control are completed and the self backup of the control system is realized. The system reliability is improved. It has important guiding significance for engineering.
