Various forms of vibrations can have a negative impact on the drilling process in rotary drilling equipment. The presence of vibrations can result in equipment damage, reduced borehole quality, decreased drilling efficiency, and increased non-productive time. Currently, the sole existing method to control these vibrations is by manually modifying drilling parameters, which is not a reliable technique and might lead to unfavourable economic consequences. Scientists have devised automated control systems to address these irregularities; however the effectiveness of the controllers is still being refined. Lately, the utilization of a PID controller based on particle swarm optimization has demonstrated noteworthy achievements. Nevertheless, the stick-slip vibration mitigation in rotary drilling equipment has not been subjected to testing. This research seeks to investigate and suggest the utilization of a PID controller, fine-tuned using the particle swarm optimization technique, to enhance the effectiveness of controllers developed for the purpose of reducing vibrations in rotary drilling systems.
