Review of Dynamic Positioning Control in Maritime Microgrid Systems

Abstract

For many offshore activities, including offshore oil and gas exploration and offshore wind farm construction, it is essential to keep the position and heading of the vessel stable. The dynamic positioning system is a progressive technology, which is extensively used in shipping and other maritime structures. To maintain the vessels or platforms from displacement, its thrusters are used automatically to control and stabilize the position and heading of vessels in sea state disturbances. The theory of dynamic positioning has been studied and developed in terms of control techniques to achieve greater accuracy and reduce ship movement caused by environmental disturbance for more than 30 years. This paper reviews the control strategies and architecture of the DPS in marine vessels. In addition, it suggests possible control principles and makes a comparison between the advantages and disadvantages of existing literature. Some details for future research on DP control challenges are discussed in this paper.

Particle Swarm Optimization of a Passivity-Based Controller for Dynamic Positioning of Ships

“…Conventional DP systems for vessels are usually designed to achieve reliable and accurate position/station keeping capabilities. It compromises the following main components being a set of dedicated modules which are a combination of propulsion and maneuvering devices and controllers [1,3]…”

“…Marine vessels and ships have been widely used for offshore exploration, deep-sea mining, military operations, rigs-drilling and offshore wind farm constructions [1]. For such activities to be operated under safe and stable conditions, the vessels need to be equipped with advanced motion-control systems [2].…”

“…A comprehensive literature survey for the control methods of DP systems until 2011 have been discussed in [3]. Further review and comparison of different control techniques have been presented in the recent review in [1]. The single-input-single-output PID control is a first reported method used for DP system regulation [1,5].…”

“…Further review and comparison of different control techniques have been presented in the recent review in [1]. The single-input-single-output PID control is a first reported method used for DP system regulation [1,5]. A low-pass filter was combined to the PID controller to control the motion of the DP system in the 3-degrees-of-freedom (DOF) horizontal plane.…”

“…Model-predictive control (MPC) is another popular control method that has recently been reported in the literature by a number of authors. Enhancement in control performance of the DP systems can be achieved deploying this method due to its systematic way in handling various (inputs, outputs and states) constraints [24], its model/performance optimization capabilities as well as its robustness against external disturbances and unmodeled dynamics [1,4]. The tracking MPC control problem of underactuated surface vessels has been proposed in [20].…”
