Abstract
In some embodiments, systems for automatically and dynamically controlling a drill string for drilling an earth formation may include a length of drill pipe, an earth-boring tool, a drawworks, a rotational apparatus, and a pump. A control unit may store software that causes the control unit to: accept a planned trajectory; divide the planned trajectory into a predetermined number of sections, normalizing the distance; receive operational state data from the drawworks, the rotational apparatus, and the pump; at least periodically calculate a normalized performance metric at least in part by dividing a raw performance metric by a distance per section; compare the calculated normalized performance metric to a benchmark performance metric; and send a control signal to cause the drawworks, the rotational apparatus, the pump, or any combination of these to automatically change an operating parameter to better match a corresponding operating parameter that achieved the benchmark performance metric.
