함안정기 개발을 위한 HILS

Abstract

A ship cruising in the ocean oscillates continuously due to wave action. In order to reduce ship’s roll motion, we developed a fin stabilizer as an anti-rolling device for 500 ton-class high speed marine vehicle. During the development phase, it was required to set up control gains for motion and hydraulic system and assess the effectiveness of anti-rolling performance on the ground. For this reason, Target Simulator, which simulates ship’s motion, receives operator’s inputs such as engine telegraph and waterjet deflection angle, and generates roll using one-degree of freedom motion base. Hardware-In-the-Loop Simulation(HILS) was performed using the Target Simulator in order to confirm the various logics of a fin stabilizer, select initial control gains, and estimate the anti-rolling performance. In conclusion, it was confirmed that HILS was very helpful to develop a fin stabilizer because it could reduce lots of sea trial tests to be needed and check many malfunctions in the factory a priori.
