Abstract

The invention discloses a spacecraft solar wing permanent magnet synchronous motor drive control system which comprises an FPGA core control module, a permanent magnet synchronous motor integrated power drive module, a position rotating transformer exciting and decoding module, a current acquisition and protection module, and a brake and clutch drive control module. According to the drive control system, with an FPGA with high efficiency data acquisition and processing ability as a control core, the integrated permanent magnet synchronous motor power drive module and a position rotating transformer angle detection module with high precision and high anti-interference ability are used, at the same time an over-current protection module with a hysteresis comparison function is designed, and thus the spacecraft solar wing drive control system has the advantages of integration, high precision, and high anti-interference ability.

Description

technical field [0001] The invention relates to a large-scale solar wing drive control technology for an aerospace system, in particular to a drive control system based on FPGA control and using a permanent magnet synchronous motor as a drive actuator for a spacecraft solar wing. Background technique [0002] In the current aerospace system, whether it is a spacecraft or a satellite, the main power to maintain its normal operation in orbit is electric energy, and the solar wing is an important energy source to realize the conversion of solar light energy into electrical energy. The size of the solar wing span is mainly determined by the power supply requirements of the spacecraft or satellite. In the past, the wingspan of solar wings was mostly a few meters or more than ten meters long. The main driving actuator was a DC brushless motor. The control core was composed of a single-chip microcomputer, DSP or FPGA. The power drive module of the motor was mostly built with discre...
