An is an automated control system used on drilling rigs (both for oil and gas exploration and scientific drilling). Its primary function is to control the weight applied to the drill bit automatically, rather than relying solely on manual manipulation by the driller. Source: Rao, S

This paper presents the design and development of an autodrilling system for oil and gas wells. The authors discuss the system's architecture, components, and control algorithms.

The difference between the pressure inside the drill pipe and the annulus, which indicates how hard the mud motor is working.
