Description

technical field

[0001] The invention relates to a low-consumption, high-reliability integrated magnetic levitation flywheel DC brushless motor control system, which realizes high-precision control of a high-speed DC brushless motor driven by a magnetic levitation flywheel, and is suitable for low power consumption, high integration, high reliability, High-precision precision spacecraft control actuators are also suitable for DC brushless motor control systems that do not require high power consumption, reliability, and integration. Background technique

[0002] The flywheel system is the key actuator for attitude control of small and medium-sized spacecraft. It generates the control torque required for attitude control of the spacecraft by changing the rotational speed of the rotor, thereby precisely controlling the attitude of the spacecraft.

[0003] The existing motor control systems for maglev flywheels are divided into two categories: analog control systems and digital ...
