摘要：
Offshore drilling platforms are exposed to wind, waves, currents, and other unknown disturbances. Accurately estimating and rejecting these disturbances is the key to ensuring reliable station -keeping of the platforms. In this study, a novel dynamic positioning method using an improved equivalent -input -disturbance (EID) approach is proposed for offshore drilling platforms. An improved EID estimator is employed to estimate and suppress unknown disturbances, significantly enhancing the disturbance -rejection performance of the dynamic positioning system. The input channels are decoupled through linear transformation, and the parameter tuning process of the observer and controller is optimized, thus improving system performance. The bounded -input bounded -output stability of the closed -loop system is proved. This study provides insights into the design of dynamic positioning systems for offshore drilling platforms.
