Abstract:

Again the backdrop of space gravitational wave detection missions, this paper reviews the cutting-edge research progress in the dynamics modeling, control strategy determination, and controller design of space inertial sensors used to provide precise inertial reference benchmarks, The paper first introduces the role and structural configuration of space inertial sensors in space gravitational wave detection missions, provides an analytical description of the sensor voltage driving process, and introduces the corresponding sensor operating modes. Then, under the configurations of two types of gravity wave detection missions corresponding to the drag-free spacecraft, the process of establishing the dynamics model of multiple test masses within the inertial sensor is described. Subsequently, in response to the requirements of the detection mission, this paper reviews the relevant issues and methods of electrostatic suspension control for inertial sensors, describes the necessity and urgency of studying the electrostatic suspension control issues for space inertial sensors, and summarizes and prospects the frontier research issues of this control technology.

Key words: space inertial sensor, spacecraft dynamics, test mass electrostatic suspension control, space gravitational wave detection, drag-free spacecraft
