Simple disturbance observer for disturbance compensation
IET Control Theory & Applications, 2010 Disturbance observer (DOB) without using additional sensors is an attractive method to attenuate the effects of disturbances as they are highly cost effective. This study proposes a simple form of DOBs, which does not need to solve the plant model inverse, and uses H∞ control method to design the Q-filter in the DOB.

Cascade Control of Active Heave Compensation Nonlinear System for Marine Crane
Journal of Marine Science and Engineering, 2023 During the rough marine environment, heave compensation is used to offset the heave motion of the vessel when a marine crane lifts and lands the load. Thus, load motion and vessel motion are realized decoupled. In previous studies, the interference items
