Integrated magnetically suspended control moment gyroscope control platform

Abstract

The integrated magnetically suspended control moment gyroscope control platform for the integrated control of the magnetically suspended control moment gyroscope system includes mainly an application layer, a system layer, a field bus and a control layer. The application layer on the control layer completes the signal data acquisition, complicated algorithm calculation and monitoring, and includes a state acquisition module, a monitoring module, a communication module and a man-machine interface module. The system layer providing the application layer with operation platform and real-time datum includes an application platform based on CORBA protocol, a RTOS and an embedded hardware system. The control layer completes the control on the current loop of the controlled parts, including FPGA motion control card based on Nios II, high speed motor, frame motor, etc. The system layer communicates with the control layer through the field bus.

Description

technical field [0001] The invention relates to an integrated magnetic levitation control moment gyro control platform, which is mainly used in attitude control systems in the field of aerospace. Background technique [0002] The control moment gyroscope is an important attitude control actuator on large spacecraft and space stations. Compared with the traditional mechanical control moment gyroscope, the magnetic levitation control moment gyroscope has the advantages of large torque output and low vibration, so it has a wide range of high-precision large satellites and space stations. application prospects. [0003] The existing magnetic levitation control torque gyroscope servo system is centralized control according to different components, such as a set of controllers for high-speed motors, a set of control systems for frame servo motors, and a set of control systems for magnetic bearings. Therefore, effective high-speed communication cannot be carried out between the co...

AI Technical Summary

Problems solved by technology

Therefore, effective high-speed communication cannot be carried out between the controlled components, and if the controlled components are changed or added, a large change must be made to the corresponding hardware

In addition, from the perspective of economy, if the existing system wants to ensure high-precision control of each controlled component, it must use a relatively advanced CPU, and using a high-speed and highly integrated CPU to control only one component will cause a large resource consumption. waste

If a high-speed and highly integrated CPU is used to control multiple components, there is a problem that the computing power of the CPU is not enough

Therefore, the existing technology has the problems of inability to carry out effective high-speed communication between the controlled components, poor system flexibility and waste of resources.
