Abstract

The invention discloses a micro / nano-satellite reaction flywheel control method based on linear Hall. The method comprises the steps of (1) acquiring an electrical angle theta and an angular velocity omega at a rotor position of a reaction flywheel motor from output signals of three linear Hall sensors distributed uniformly along the same circumference; and (2) obtaining a reference signal of a three-phase current control instruction for a stator of the reaction flywheel motor from the output signals of the three linear Hall sensors, thus controlling a reaction flywheel. The micro / nano-satellite reaction flywheel control method based on linear Hall is low in cost, stable in control effect and high in 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 import...
