Design and Analysis of 777 'Fly-by-Wire'Control System.

摘要

This document describes the design and implementation of the 'fly-by-wire' despin control system for Program 777. Two designs for the ground loop controller are considered - one using proportional control only and one using proportional plus rate control. It is recommended that the spacecraft be operated at the lower RPM's. Also, recommended are counter limits to minimize transient overshoots to large torque disturbances. (Author)
