三轴卫星天线降低能耗研究

Research for energy consumption reduction of tri-axis satellite antenna

针对三轴遥感卫星天线用户任务逐渐增多,消耗的能源越来越多的现状,简要介绍了天线控制系统的功能和组成。以功耗测试数据为依据,分析了三轴遥感卫星天线的能耗情况,从缩短天线闭环等待时间、第三轴下电抱闸等方面讨论了降低功耗策略和措施,并提出一种智能化力矩偏置控制的设计,通过智能力偏设置电路去除力矩偏置值,有效控制和降低设备的能耗。

As the use of tri-axis remote sensing satellite is increasing, energy consumption is going high. The paper briefly describes the composition and function of the antenna control system. To deal with this situation, the power test data is employed to analyze the energy consumption of tri-axis remote sensing satellite antenna. Besides, from the aspects of shortening the closed loop waiting time of antenna, a tri-axis to brake, strategies and measures are discussed to reduce energy consumption. An intelligent torque bias control is designed to reduce the torque bias value. Therefore the energy consumption of equipment can be effectively controlled and reduced.
