Claim 15:
16. A computer-readable medium having computer program code stored thereon and configured when executed by one or more processors to cause the one or more processors to perform a method for controlling a drilling operation, comprising:
determining a difference between a differential pressure and a target differential pressure,
wherein the target differential pressure is less than a differential pressure limit; and
adjusting a weight on bit setpoint as a function of the difference between the differential pressure and the target differential pressure so as to adjust the differential pressure and thereby reduce the difference between the differential pressure and the target differential pressure,
wherein adjusting the weight on bit setpoint comprises:
determining a relationship between a weight on bit and the differential pressure; and
adjusting the weight on bit setpoint based on the relationship, wherein adjusting the weight on bit setpoint based on the relationship comprises:
determining a target weight on bit based on the relationship;
determining an adjustment to be made to the weight on bit setpoint based on the target weight on bit; and
adjusting the weight on bit setpoint based on the determined adjustment.
