PID-Based Kalman Filter Controller Design Stick-Slip Vibrations Suppression in Drill String Systems

Vibrations caused by stick-slip, which are common in rotary drilling systems, have a major effect on drilling efficiency. They also seriously damage equipment and lower hole quality. In order to precisely estimate the drilling tool velocity, we investigate the use of the Kalman filter in this study. The Kalman filter is a crucial tool for effective control strategies because it provides accurate velocity estimates by continuously monitoring system dynamics using sensor data. These approximations are easily incorporated into a PID (proportional-integral-derived) control system. The PID controller dynamically modifies drilling parameters, such as torque, based on state estimates in order to effectively counter stick-slip vibrations. Based on thorough simulations, our suggested method shows observable decreases in stick-slip vibrations, which translates into significant improvements in drilling effectiveness, decreased equipment wear, and improved hole quality. Furthermore, the controller's ability to adjust to different drilling conditions highlights how versatile it is as a workable solution in a range of drilling scenarios. This combination of robust control strategies and state estimation techniques offers a promising way to deal with stick-slip-induced problems in rotary drilling systems, which will ultimately lead to more dependable and efficient drilling operations.
