Abstract:
A general approach for the attitude control of directional drilling tools for
the oil and gas industry is proposed. The attitude is represented by a unit
vector, thus the non-linearities introduced by Euler angle representations are
avoided. Three control laws are proposed, and their stability is proven. Their
behaviour is tested by numerical simulation. The merits of the laws from an
engineering perspective are highlighted, and some details for the implementation
of the laws on directional drilling tools are provided.
