Abstract

The invention discloses a high-precision vibration isolation satellite and a control method thereof, and relates to the field of satellite vibration isolation control. The satellite comprises a satellite platform and a load platform, the satellite platform is connected with the load platform through an active vibration isolation control device, and a quality inspection and drag-free control deviceand an electrostatic suspension control device are arranged in the satellite platform; when the satellite is in an on-orbit flight process, the active vibration isolation control device is used for actively isolating high-frequency vibration between the satellite platform and the load platform; the drag-free control device is used for controlling the satellite platform to move along with the inspection mass, and the electrostatic suspension control device is used for controlling movement of the inspection mass. According to the high-precision vibration isolation satellite, full-band vibrationattenuation of the satellite is achieved, the load platform has the rapid high-precision attitude maneuver capacity, and the requirements of loads for the high microgravity level and high-precision rapid pointing are met.

Description

technical field [0001] The invention relates to the field of satellite vibration isolation control, in particular to a high-precision vibration isolation satellite and a control method thereof. Background technique [0002] At present, with the in-depth development of space science research and space technology applications, higher index requirements are put forward for aerospace technology, such as high microgravity level, high precision, high stability, and fast tracking control with large attitude angles. Due to the disturbance of the external environment such as atmospheric resistance and solar light pressure, the spacecraft’s in-orbit operation, and at the same time, due to its own load action, flutter of flexible parts, and attitude control engine work, etc., will produce different degrees of disturbance, thus destroying the spacecraft. Microgravity level and high precision and high stability control performance. [0003] Existing satellites cannot isolate low-frequen...
