Embodiment Construction

[0020] The dual-frame magnetic levitation variable speed control torque gyro is composed of magnetic bearings, high-speed motors and inner and outer frames in the system. It can not only output large torque by changing the angular momentum direction of the magnetic levitation rotor (rotating frame), but also output high-precision torque by changing the rotor speed. A single double-frame maglev variable speed control control torque gyro can output three-axis control torque to realize the three-axis attitude control of the spacecraft.

Abstract

The invention relates to an integrated digital control system for a double gimbal magnetically-suspended variable-speed control moment gyroscope. The integrated digital control system mainly comprises a DSP and peripheral module thereof, an FPGA module, an interface circuit, a signal conditioning circuit, a power amplification module, an RS422 communication interface module. The control system obtains signals through the interface circuit and outputs the signals to the DSP; the DSP generates magnetic bearing, high-speed motor and frame system control quantity through a control algorithm and outputs the magnetic bearing, high-speed motor and frame system control quantity to the FPGA module; the FPGA module carries out PWM modulation on the control quantity and outputs PWM signals to the power amplification module, thereby realizing the integrated control of a magnetic bearing, a high-speed motor and a frame system. Besides, the real-time communication between the DSP and an upper computer is realized through the RS422 communication interface module, thereby realizing on-line adjustment of control parameters and on-line monitoring of the running status. The integrated digital control system helps to realize the high-precision high-reliability integrated control of the double gimbal magnetically-suspended variable-speed control moment gyroscope, and effectively helps to reduce the size, the weight and the cost of the control system.
