Rotation Speed Measurement for Heading Control of a Small Robotic Airship

摘要

There exists an immense potential for the use of small robotic airships for anti_terrorism, traffic observation, climate monitoring, etc. For these missions, the stable heading control of a robotic airship is needed. In fact there is heading angle error because of the rotation speed difference of the two engines on the sides of the gondola. The heading angle error forces the robotic airship to leave from the given course. In this paper, real_time rotation speed measurement of two engines is presented in order to eliminate the rotation speed difference.
