چکیده

This paper describes the Variable Speed Control Moment Gyroscope (VSCMG) Workbench, a simulation software tool developed at Georgia Tech. This program will provide the Air Force Research Laboratory (AFRL) with a tool for studying spacecraft control system design for vehicles equipped with VSCMG actuators for combined attitude control and energy storage.

New Startup Method Using Internal Momentum Management of Variable-Speed Control Moment Gyroscopes

An initial startupmethod for a spacecraft actuated by a pyramidal arrangement of variable-speed controlmoment gyroscopes is developed. The method provides closed-loop internal momentum tracking control to enable the flywheels to start from rest and reach desired wheel speeds. The proposed controller functioning as a variable-speed control moment gyroscope steering law is developed in terms of t...

Dynamics and Control of a Rigid Spacecraft with a Control Moment Gyroscope

The attitude dynamics of a spacecraft with a variable speed control moment gyroscope (CMG), in the presence of conservative external inputs, are derived using variational principles. A complete dynamics model, that relaxes some of the assumptions made in prior literature on control moment gyroscopes, is obtained. These dynamics equations show the complex nonlinear coupling between the internal ...

Mechatronics Architecture of Smartphone-Based Spacecraft ADCS using VSCMG Actuators

Hardware and software architecture of a novel spacecraft Attitude Determination and Control System (ADCS) based on smartphones using Variable Speed Control Moment Gyroscope (VSCMG) as actuator is proposed here. A spacecraft ground simulator testbed for Hardware-in-the-loop (HIL) attitude estimation and control with VSCMG is also described. The sensor breakouts with independent micro-controller ...

Test and Analysis of Micro-vibrations Generated by Large Control Moment Gyroscope

Control moment gyroscope (CMG) is widely used as an actuator of spacecraft attitude control Micro-vibrations generated by CMG will influence the performance of high-sensitivity instruments on-board the spacecraft; however, the micro-vibrations characteristics of CMG are not yet clearly understood. This paper concentrates on testing and analyzing the micro-vibrations produced by CMG. Firstly, fo...

Attitude Dynamics/Control of Dual-Body Spacecraft with Variable-Speed Control Moment Gyros

The dynamics equations of a spacecraft consisting of two bodies mutually rotating around a common gimbal axis are derived by the use of the Newton–Euler approach. One of the bodies contains a cluster of single-gimbal variable-speed control moment gyros. The equations include all of the inertia terms and are written in a general form, valid for any cluster configurations and any number of actuat...
