Description

technical field [0001] The invention relates to a magnetic levitation control moment gyro monitoring system, in particular to a magnetic levitation control moment gyro monitoring system for simulating rocket launch and in-orbit operation. Background technique [0002] The magnetic levitation control torque gyro adopts the bearing support method of magnetic levitation. Compared with the mechanical control torque gyro supported by the mechanical ball bearing, it avoids the wear of the mechanical bearing itself due to friction, so it has the advantages of long life, low vibration, high speed, etc. It is a large aerospace It is an important attitude control actuator on aircraft and space stations, and has broad application prospects. [0003] In the research and development and testing phase of the magnetic levitation control torque gyro on the ground, it is necessary to test various indicators in the two states of rocket launch and orbit operation to evaluate the performance of...

Problems solved by technology

[0003] In the research and development and testing phase of the magnetic levitation control torque gyro on the ground, it is necessary to test various indicators in the two states of rocket launch and orbit operation to evaluate the performance of the magnetic levitation control torque gyroscope. The existing magnetic levitation control torque gyroscope adopts decentralized control , The magnetic bearing device, high-speed motor device, frame servo device and locking and unlocking device each have an independent control and communication system. The computer is used to control and detect the working status of each system independently, and it is impossible to detect the overall performance of the magnetic levitation control torque gyroscope. Control and evaluation, the maglev control moment gyroscope also communicates with the on-board computer as a whole when it is actually used, so the existing decentralized communication and control methods cannot simulate the real working conditions of the maglev control moment gyroscope
