An Adaptive PID Switching Controller for Pressure Regulation in Drilling
نویسندگان
چکیده
Managing well pressure in petroleum drilling is essential for avoiding instability. An adaptive PID control using the unfalsified procedure is proposed to regulate the pressure. The scheme chooses the right PID parameter from a set of candidate parameters based on the data measurement instead of any hypothetical model. The scheme eliminates the difficulties in tuning the PID even without any prior knowledge of the system to regulate and results in fast controller adaptation.
