AUTOMATIC SYSTEM FOR ADVANCED SPEED CONTROL OF THE DRILLING HOE

Drilling consists of the operation of creating a well, which involves a complex set of activities. In a narrower sense, it includes the dislocation of rocks and the extraction of rock fragments to the surface. A drilling tool called a bit is used to dislodge rocks, being connected to the surface drilling rig via a drill string. Automating the processes associated to drilling is extremely important to ensure its development in optimal conditions. This work is focused on the control of the drilling hoe rotation speed, in order to damage it as little as possible
