In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer earthbath facial wipes equipment and person to SES.For this purpose, an LQR control system is designed to damp the vertical motion of the surface effect ship in critical sea states including high-frequency and high amplitude regular waves as well as virginia mill works tobacco road acacia high frequency irregular waves.The simulation results show the high quality of the system control in the studied sea condition.A comparative analysis of LQR and PID approaches demonstrate the high performance of the new designed control system.

The proposed controller outperforms the traditional PD.
