Title:
DEEP-SEA CRANE ACTIVE HEAVE COMPENSATION CONTROLLER AND CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/012962
Kind Code:
A1
Abstract:
A deep-sea crane active heave compensation controller and control system. The deep-sea crane active heave compensation controller has a dual-loop control structure. The outer loop control structure is an active disturbance rejection controller, and used for compensating for external disturbance and generating a desired angle for an inner loop; the inner loop control structure is an equivalent saturation model predictive controller, and used for compensating for the input saturation and dead zone characteristics of an electro-hydraulic servo winch to ensure that the electro-hydraulic servo winch can track the desired angle quickly and accurately.
