abstract = "During the voyage, the ship is affected by waves, sea breeze and other factors, causing the ship to sway and produce vibration. The series-parallel three-degreeof- freedom stability platform is mainly a light guiding device for the sliding roll indicating system, which has the functions
of isolating the hull pitching, rolling motion and adjusting the azimuth according to the direction of the helicopter. It is based on this function that makes the stable platform have a wide range of applications. This paper analyzes the overall structure and control scheme of the series-parallel
platform, based on the wave spectrum density formula recommended by ITTC, digitally simulates the pitch and roll motion of the ship; performs dynamic and kinematic modeling analysis on the parallel platform, analyzes the interference and other phenomena. Based on dSPACE to build a semi-physical
simulation platform, the HIL experiment is carried out on the prototype of the marine series-parallel stable platform. The stable platform is installed on the swinging platform, and the actual operating environment is simulated by the swinging table to simulate and analyze the actual operation.",
