Releasing the test mass (TM) is a critical phase of inertial sensors for gravitational wave detection. The grabbing positioning and release mechanism inevitably generates large initial momentum making TM capture control particularly challenging. To maximize the controllable range, this paper presents a time-division control strategy for the TM release phase. Simulation results show that the proposed method significantly enlarges the capture range, enabling robust capture under large initial state.

空间惯性传感器质量释放阶段的最大测距时分控制设计

释放测试质量（TM）是惯性传感器用于重力波探测的关键阶段。抓取、定位和释放机制不可避免地会产生较大的初始动量，使得捕捉控制变得尤为具有挑战性。为了最大化可控范围，本文提出了 TM 释放阶段的时分控制策略。模拟结果表明，所提方法显著扩大了捕获范围，使得在大初始状态下实现稳健捕获。
