Integrated digital control system for double gimbal magnetically-suspended variable-speed control moment gyroscope

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.
