| Research Abstract |
The conventional method to estimate NOMOTO models for ships based on Zig-Zag maneuvers doesn't work very well under disturbances of current. In the research, we have tried to develop a new method based on closed loop identification which is applicable under disturbances. Using computer simulations, we have shown that NOMOTO models via the proposed method is superior as nominal models in control systems design to those via Zig-Zag maneuvers, although the latter can represent Zig-Zag maneuvers very well.
