“…Tang [10] used a particle swarm optimization algorithm to optimize the control cofficients of the controller to improve the effect so that the system had the advantages of subtle overshoot and ripid response time. Richter [11] used secondary components to drive the winch to evaluate the compensation and accuracy of the system on the test bench. Haria [12] elaborated on the new switching mode of hybrid electric vehicles based on the secondary regulation system.…”

Aiming at the problem that the widely used heave compensation technology is difficult to balance the compensation effect and energy consumption, based on the secondary regulation technology, the fuzzy PID control method is selected to design a winch heave compensation system with energy recovery. Firstly, a mathematical model is established and analyze the energy-saving characteristics of the heave compensation system. Then, the swash plate controller and speed outer loop controller are designed, and the simulation is model with the AMESim-MATLAB co-simulation platform. Finally, the simulation results are tested by experiments. And the test result reflects that the compensation efficiency of the compensation is more than 90%, and part of the energy can be recovered. The controller has good control accuracy and stability. The compensation system can effectively compensate for the position deviation caused by waves, thus providing a safety guarantee for offshore operations.

“…The installation of a lifting compensation system can also reduce stress changes inside the umbilical cable and prevent it from fraying [28];A high-precision sinking compensation system can allow the ROV to work normally under complex sea conditions, shorten the construction period, and improve work efficiency. Engineers have spent a significant amount of time designing the passive lifting compensation system (PHC) [29,30], the active lifting compensation device (AHC) [25,31,32], and the active-passive joint lifting compensation system (APHC) [33,34]. Because of its current nonlinear control and sensor technology, the active sinking compensation system has the most effective compensation effect [35].The mother ship sinking motion prediction technology is added to the active sink compensation system to improve compensation accuracy.…”

This study develops an event-triggered controller for the ROV attitude system. First, the dynamic modeling of ROV attitude control is performed. The three-dimensional dynamic equation for ROV attitude control is obtained by decoupling each degree of freedom, and the model for the ROV attitude stability control system is obtained by taking into account the influence of ROV hydrodynamics, ship movement, and umbilical cable vortex-induced vibration. The ROV attitude stability control controller is designed by using backstepping control and sliding mode control, the event trigger mechanism is added to optimize its control output, and the Volterra adaptive multi-step prediction algorithm is designed to predict the ship sinking time series in advance, and the condition parameters are provided for the event trigger mechanism in the AHC controller to improve the positioning accuracy of the attitude stability axial subsystem (AHC). The simulation findings demonstrate that the control strategy and prediction algorithm developed in this study can accomplish the control task and have a strong anti-interference ability by establishing varying degrees of sea conditions and advanced forecast time for simulation tests. Additionally, the event trigger mechanism optimizes the control law, better utilizes the output control signal's channel, and prevents the control output from acting improperly, all of which can reduce network bandwidth use.

“…Dynamic modeling of the shipboard cranes with wave compensation is an important aspect of the research on various cranes. Wave compensation is mainly divided into three categories: passive compensation [4][5][6], active compensation [7][8][9], and semiactive compensation [10][11][12]. Wave compensation [13][14][15] is the earliest technology applied to ensure the safety of ships at sea in severe weather [16].…”

In order to explore the dynamic characteristics of the telescopic sleeve antiswing device for shipboard cranes under coupling excitation, a three-dimensional dynamic model of the ship crane telescopic sleeve antiswing device is established in this study, and the accuracy of the model is verified through experiments. By dynamic analysis, the influence of sleeve extension and contraction, damper parameters, and ship excitation on the payload swing is found; meanwhile, the influence of payload swing on ship stability is discovered. At the same time, the simulation results show that the three-dimensional dynamic model can accurately simulate the swing reduction characteristics of the antiswing device. The in-plane and out-plane angles of the swing are reduced by 70% and 90%. The research results have great significance to further explore the antiswing mechanism and structural design of the mechanical antiswing device.
