“…For the ship stabilization control research, the basic algorithms used include PID [79], fuzzy logic control [80], predictive control [81], sliding mode control [82], ADRC [83], etc. On this basis, an optimization algorithm is combined with a basic algorithm, such as GA and PID [79], artificial bee colony(ABC) and ADRC [84].…”

“…However, in the later stage of SMC, because the system state traverses the hyperplane back and forth, the system structure changes constantly, and the control quantity will be chattering constantly, which is also a problem in the practical application of SMC. SMC algorithm has a better control effect on large ships such as maneuverability (such as VLCC) [139], Multi-ship coordinated positioning [82] and docking [54] under low-speed, non-linear and environmental disturbances.…”

At present, with the development of waterborne transport vehicles, research on ship faces a new round of challenges in terms of intelligence and autonomy. The concept of maritime autonomous surface ships (MASS) has been put forward by the International Maritime Organization in 2017, in which MASS become the new focus of the waterborne transportation industry. This paper elaborates on the state-of-the-art research on motion control of MASS. Firstly, the characteristics and current research status of unmanned surface vessels in MASS and conventional ships are summarized, and the system composition of MASS is analyzed. In order to better realize the self-adaptability of the MASS motion control, the theory and algorithm of ship motion control-related systems are emphatically analyzed under the condition of classifying ship motion control. Especially, the application of intelligent algorithms in the ship control field is summarized and analyzed. Finally, this paper summarizes the challenges faced by MASS in the model establishment, motion control algorithms, and real ship experiments, and proposes the composition of MASS motion control system based on variable autonomous control strategy. Future researches on the accuracy and diversity of developments and applications to MASS motion control are suggested.

“…Basically, the ship to be launched has a cost that is quite expensive, so the launching process based on experimental experience needs to be minimized. What is of concern in the launching process is the ship's radio to be launched where the ratio of length to width is small, the conditions of the launch pad and water conditions are less than ideal (Ianagui & Tannuri, 2015;Thomas et al, 2009). The previous research, entitled "A recovery system for the key components of the first stage of a heavy launch vehicle," by Casper Dek, presents a comparative calculation of the launch diagram between conventional and airbag systems.…”

In a ship planning can not be separated from the planning of the ship launching process. A ship can glide perfectly if it has a high enough planning time and costs. The launch process itself is divided into several ways. The choice of this method needs to be considered because it relates to the budget and preparations made. The method used is the calculation according to the numerical approach assisted by computational software. In the first calculation it is planned with the slipway launch, and then the next one is planned with the airbags that have been implemented previously. The purpose of this study is to provide analysis results as a consideration in implementing the slipway and airbag ship launching method on KM ships. Belt Nusantara 72 measuring 2000 DWT. In steps 5 to 6, both the slipway and the airbags experience a stern lift condition with a value (yVd) of 1396.97 ton. Based on the economic analysis of the hours of people using airbags, there is a decrease in working hours by 44% when compared to the launch using a slipway. This also happened to work productivity where it was 84% more time effective. When viewed from an investment point of view, the use of slipways is actually more economical than airbag, the difference is 43% more economical using slipways. Both types of launch can be applied by looking at the economical side and the ability of each shipyard in carrying out the launching process and seeing the main size of the ship to be launched.
