Design of tracking system of telemetering antenna in pilotless aircraft

摘要

In this paper, the design plan of the tracking system of the telemetering antenna in a type of pilotless aircraft is introduced. The discussion centres on the controls. Then the format of control words and an algorithm, which are effectively used to control the stepping motor are given. This algorithm has a function of parallel control and has already been used in our research. The design of the antenna servo system and the fining step pitch (FSP) control of the stepping motor will benefit from this paper.
