The effect of PID control scheme on the course-keeping of ship in oblique stern waves

Autor: Yunbo Li, Zongyu Tang, Jiaye Gong

Publikováno v: Brodogradnja, Vol 74, Iss 4, Pp 155-178 (2023)

Sailing in oblique stern waves causes a ship to make sharp turns and uncontrollable course deviation, which is accompanied by a large heel and sometimes leads to capsizing. Studying the control algorithm in oblique stern waves is imperative because a

Investigation on the Radar Scattering and Doppler Spectrum From Trimaran Based on the Motion of Six Degrees of Freedom

Autor: Yuxin Deng, Jinxing Li, Wangqiang Jiang, Min Zhang

Publikováno v: IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Vol 16, Pp 6889-6901 (2023)

The trimaran is an advanced ship with high hydrodynamic performance, but the study of its electromagnetic characteristics and Doppler spectrum is insufficient. This study presents a new procedure for evaluating the scattering echo and Doppler spectru

Numerical study of trimaran wave load based on time-domain Rankine method

Autor: Haoyun Tang, Qian Wan, Huilong Ren

Publikováno v: Brodogradnja, Vol 74, Iss 3, Pp 107-129 (2023)

Due to the complex fluid interference between outrigger and main hull, it is difficult to predict the trimaran load fluctuation accurately in different marine environments. Therefore, a time-domain Rankine method is developed to improve the accuracy
