Problems solved by technology

[0003] (1) Compared with the momentum wheel, the torque output accuracy of the control torque gyroscope is relatively low. In order to further improve the torque output accuracy of the control torque gyroscope, it is necessary to improve the speed control accuracy of the outer frame of the control torque gyroscope
[0004] (2) Generally speaking, DSP or DSP+FPGA is used as the controller for the drive and control of the outer frame of the control moment gyroscope, but the cost of this high-level DSP chip is high

Abstract

The invention relates to a drive control system and method for a control moment gyro outer frame. The drive control system comprises a position detection module used for detecting the position information of the control moment gyro outer frame; a current detection module used for detecting two-phase current information of a control moment gyro outer frame motor; a position control module used forreceiving a position control signal and outputting a speed control signal according to the position information detected by the position detection module; a speed control module used for receiving a speed control signal and outputting a current control signal according to the position information detected by the position detection module; and a current control module used for receiving a current control signal and carrying out drive control on the control moment gyro outer frame according to the two-phase current information detected by the current detection module and the position informationdetected by the position detection module. The control system and the control method not only improve the accuracy of the system, but also greatly improve the reliability and response width of the system.

Description

technical field [0001] The invention relates to the technical field of satellite control, in particular to a drive control system and method for controlling the outer frame of a moment gyroscope. Background technique [0002] Existing actuators for satellites generally use momentum wheels or control moment gyroscopes. Compared with momentum wheels, control moment gyroscopes have the advantages of large output torque and good maneuverability. But still there are following deficiencies: [0003] (1) Compared with the momentum wheel, the torque output accuracy of the control torque gyroscope is relatively low. In order to further improve the torque output accuracy of the control torque gyroscope, it is necessary to improve the speed control accuracy of the outer frame of the control torque gyroscope. [0004] (2) Generally speaking, DSP or DSP+FPGA is used as the controller to control the drive and control of the outer frame of the torque gyroscope, but the cost of this high-l...
