英文摘要	Inertial sensors are widely used to measure small disturbances in acceleration caused by non-conservative forces in space and to realize the drag-free control of spacecrafts in scientific experiments, such as earth gravity field inversion and equivalent principle verification. In the space gravitational wave detection researchbeing carried out at home and abroad, the inertial sensor is used as the core measurement load to shield external noise and achieve free-fall motion of the Test Mass in the direction of the space sensitive axis through electrostatic control. In this paper, on the basis of the electrostatic suspension inertial sensor capacitor structures, with consideration to the working principle of the electrostatic force driving control system and based on actual processing conditions, the source of error in the system asymmetry is analyzed. Through comparative analysis of the system's performance effects on various asymmetry conditions, the asymmetry of the electrods is obtained, especially in the range of high loss in performance. On this basis, combined with the actual processing conditions, the basic requirements to control the dimensional error of the machining line within 10 m and the area asymmetry between 1% and 2% are obtained, so as to reduce the measurement range limitation of the system and improve its scientific goal. 2019, China Science Publishing & Media LTD.
