Abstract
An autotuner control system may be implemented to monitor and control operation of a drilling system and one or more drilling parameters during drilling operations. The control system may be a proportional integral derivative (PID) controller or a proportional integral (PI) controller, which can run iteratively during drilling operations to adjust drilling parameters and/or the controller. The PI or PID controller may apply adaptive filters to update and adjust one or more controller parameters (PID or PI), to autotune such parameters and may incorporate a stability constraint filter to constrain said adaptive filter, such as to reduce the impact of dead time and process time delays and adjust drilling parameters to match the drilling goals.
