Single Neuron PID-Based Heave Compensation Control for Drill String System in Oceanic Drilling

During offshore exploration operations, vessels experience six degrees of freedom motion due to wind, waves, and currents. Among these motions, heave is particularly challenging to compensate for and significantly impacts the drilling process. This paper presents an active heave compensation control method for drill string systems in offshore exploration. To address parameter uncertainties, a single-neuron PID control approach based on a quadratic performance index is proposed. A simulation analysis was conducted using MATLAB software. The results demonstrate that the proposed controller provides smoother outputs than alternative controllers, highlighting its effectiveness in heave compensation.
