1. A system to optimize a drilling parameter of a drill string, the system comprising:
a drill string control subsystem; and an optimization controller to coordinate operations of the drill string control subsystem during a drilling process at least in part by:
determining a first optimized rate of penetration based, at least in part, on a drilling parameter model and a first drilling parameter estimate;providing a first set of commands to the drill string control subsystem based, at least in part, on the first optimized rate of penetration;determining a second drilling parameter estimate during the drilling process based, at least in part, on the drilling parameter model and feedback corresponding to the drill string control subsystem;determining a second optimized rate of penetration during the drilling process based, at least in part, on the second drilling parameter estimate; andproviding a second set of commands to the drill string control subsystem based, at least in part, on the second optimized rate of penetration. |
