Abstract

The linear Hall-based micro-nano-satellite reaction flywheel control method of the present invention includes: (1) obtaining the electrical angle and the rotor angular velocity of the rotor position of the reaction flywheel motor from the output signals of three linear Hall sensors uniformly distributed along the same circumference; 2) The reference signal of the three-phase current control command of the stator of the reaction flywheel motor is obtained from the output signals of the three linear Hall sensors, so as to realize the control of the reaction flywheel. The linear Hall-based micro-nano satellite reaction flywheel control method of the present invention has low cost, stable control effect and high driving efficiency.

Description

technical field [0001] The invention relates to a reaction flywheel, in particular to a linear Hall-based micro-nano satellite reaction flywheel control method. Background technique [0002] In the past two decades, technologies such as microelectronics, micromechanics, computers, communications, and energy have made rapid progress. By adopting these high technologies, the weight and volume of satellites with the same function have been greatly reduced, and micro-nano satellites with more comprehensive functions have emerged. Satellites and even pico-satellites. Micro-nano satellites have many incomparable advantages over large satellites, such as small size, light weight, low development and launch costs, and short development cycles. Due to the adoption of new design ideas, new technologies, and new management modes of manufacturing and production, micro-nano satellites have become the most active, challenging and promising space technology field, and are also an importan...
