Design of Classical Washout Algorithm for Six Degree of Freedom Ship Motion Simulator

Abstract

The motion washout aims to bring the actual movement of the ship back to the six degree of freedom motion simulator, and to provide as real motion as possible in the limited space of the simulator. The emphasis of the classic washout algorithm lies in the choice of parameters. This paper analyzes the time domain response of the filter and combines the platform motion range with the human sensory system threshold to impose performance requirements on the system. To optimize the parameter selection according to the system performance, and get a good result of motion washout.
