Abstract

A digital device for accurately controlling frame servo system of torque gyro is featured as obtaining current, rotary speed and position signal of frame servo motor by DSP system through interface circuit; carrying out operation as per certain control algorithm to generate out control amount to be PWM-modulated; transmitting modulated PWM signal to single-phase contra variant bridge circuit by driving circuit for generating control current required by frame servo motor so as to realize accurate control of frame servo system.

Description

technical field [0001] The invention relates to an integrated high-precision control torque gyro frame servo digital control device, which is used for high-precision control of the magnetic levitation control torque gyro frame servo system, and is especially suitable for precision spacecraft with low power consumption, high integration and high precision Control the actuator. Background technique [0002] The control moment gyroscope is the basic attitude control actuator on large spacecraft and space stations. Compared with the traditional mechanical control moment gyroscope, the magnetic levitation control moment gyroscope has the advantages of large torque output and low vibration, so it has a wide range of applications on high-precision large satellites prospect. In addition, the magnetic bearing support has no friction, which avoids the wear of the mechanical bearing itself due to friction. Its reliability depends on the reliability of the electronic components of the ...
