Synthesis and development procedure of microprocessor software program for spacecraft digital attitude control
Abstract
A systematic procedure is developed for the synthesis of attitude control software for three-axis stabilized satellites. In discussing the systematic procedure, emphasis is placed on the fixed-point arithmetic scaling strategy, and three types of simulation. These simulation processes are: numerical simulation on a large-scale digital computer; full-instruction simulation for the digital controller with dynamics simulated numerically; and hardware simulation using an airbearing table on which are mounted sensors, actuators, and a microcomputer adopted for the prototype attitude controller.
