Performance Testing of a Magnetically Suspended Double Gimbal Control Moment Gyro Based on the Single Axis Air Bearing Table
Integrating the advantage of magnetic bearings with a double gimble control moment gyroscope (DGCMG), a magnetically suspended DGCMG (MSDGCMG) is an ideal actuator in high-precision, long life, and rapid maneuver attitude control systems. The work presented here mainly focuses on performance testing of a MSDGCMG independently developed by Beihang University, based on the single axis air bearing...
متن کاملModelling of Gimbal Control Moment Gyro and Analysis of Gimbal Disturbance Impact
Original scientific paper Control Moment Gyroscope is one of the main sources of disturbance affecting the accuracy of attitude control system in the spacecraft. This paper concentrates on analysing and testing the micro-vibrations produced by CMG. To analyse its disturbance features systematically, the mechanical features of flywheel, frame and the entire CMG will be firstly studied, and then ...
متن کاملSimulation and Modelling of Nonlinear Magnetics
Version 1b, August 1994 A procedure for modeling and simulation of arbitrary nonlinear magnetics components is presented. A set of electromagnetic primitives is described as implemented in Verilog-A. The primitives include cores, gaps, and windings that are combined to model ferromagnetic inductors and transformers. The physics of the ferromagnetic core model is described. The model is used to ...
متن کاملResearch on Modeling of the Agile Satellite Using a Single Gimbal Magnetically Suspended CMG and the Disturbance Feedforward Compensation for Rotors
The magnetically suspended Control Moment Gyroscope (CMG) has the advantages of long-life, micro-vibration and being non-lubricating, and is the ideal actuator for agile maneuver satellite attitude control. However, the stability of the rotor in magnetic bearing and the precision of the output torque of a magnetically suspended CMG are affected by the rapid maneuvers of satellites. In this pape...
متن کاملAdvance Modelling and Simulation of Industrial Boilers
This paper presents some of the results of the simulation in the radiation section of an industrial boiler using an advanced mathematical model. Calculations are described for the flow, heat transfer, and chemical reaction processes occurring within a gas-fired cylindrical furnace. The calculation procedure is a two dimensional one in which the main hydrodynamic variables are the velocity and s...
