中文摘要: 面向空间引力波探测需求,开展了空间惯性传感器控制策略分析,分析了极板控制和自由度控制两种控制模式的影响,以及分频控制和分时控制的优选方案。在分频控制中,对交流频率的选择、频率间隔对控制精度的影响进行了讨论。结果表明,空间惯性传感器的非敏感轴采用静电反馈控制环路,基于分频控制模式,实现交流反馈控制。
Abstract:This article focuses on the demand for space gravitational wave detection and analyzes the control strategy of space inertial sensors. The effects of two control modes, electrode control and degree of freedom control are analyzed, as well as the optimal solutions for frequency division control and time division control. In frequency division control, the selection of alternating current frequency and the impact of frequency interval on control accuracy are discussed. The analysis results show that the electrostatic feedback control loop is used for the non-sensitive axis of the space inertial sensor. A frequency division control mode is chosen to achieve alternating current feedback control.
