Embodiment Construction

[0032] Such as figure 1As shown, it is a structural block diagram of the present invention, including a dual-motor structure module, a winding switching module, a driving module, a current detection module, a current detection switching module, a grating angle measurement module, and a controller module. The dual-motor structure module includes a high-torque permanent magnet motor and a high-precision permanent magnet motor. The two motors share a permanent magnet rotor. The stator winding of the high-torque permanent magnet motor is a large winding, and the stator winding of a high-precision permanent magnet motor is a small winding. The number of turns of the former is It is more than 10 times that of the latter, and the stator windings of the two motors are separated; the winding switching module uses three relays to control the three-phase winding gating of the high-torque permanent magnet motor and the high-precision permanent magnet motor. When using the high-torque worki...

Abstract

A CMG low-speed framework rapid wide torque range and high-precision driving control system employs a dual-winding motor mode, one mode can provide a large moment, and the other one can provide a high-precision moment, two motors can perform free switching according to an operating condition, and therefore, the CMG low-speed framework rapid wide torque range and high-precision driving control system has a wide torque range and a high-precision moment output capability, and can satisfy maneuverability demands for multi-task realization for the future and demands of a super quick high-performance satellite platform capable of imaging with moving.

Description

technical field [0001] The invention relates to a CMG low-speed frame fast, wide torque range, and high-precision drive control system, which belongs to the technical field of control moment gyroscopes. Background technique [0002] Facing the needs of mobility and flexibility for future multi-task realization, ultra-agility, and high-performance satellite platforms such as imaging in motion, it is necessary to comprehensively improve the performance of satellite platforms from the three aspects of "fast, stable, and precise" so that it can be used in my country's ultra-high-precision Fields such as earth observation satellites have shown a wide range of application values. In order to achieve this goal, it is required that the attitude control actuator can quickly provide a fast, large and high-precision output torque. [0003] At present, the development of medium-sized control moment gyroscope has been carried out, and its angular momentum and output torque are difficult ...
