چکیده
This paper proposes a nonlinear dynamics model for a marine propeller able to reproduce the propeller thrust over the full four-quadrant range of propeller shaft speed and vessel speed. A two-state model has been identi ed from experimental data. The model includes a state equation for the propeller shaft speed and one that describes the dynamics of the axial ow velocity. The model reproduces accurately propeller thrust and torque over a wide range of operation. Keywords: Identi cation, marine, modeling, nonlinear, propulsion

A Four-Quadrant Thrust Estimation Scheme Based on Chebyshev Fit and Experiment of Ship Model
This paper proposes a thrust estimation scheme for marine propellers in four-quadrant operations. To calculate the thrust and torque coefficients of screw propeller in four-quadrant, a Chebyshev fit expression of the propeller properties in four-quadrant for surface vessel is given, and then it is changed into an ordinary polynomial expression. These expressions are suitable for calculating the...

In this paper a recently reported four-quadrant nonlinear thrust controller for marine propellers is applied to the velocity control of an underwater vehicle. The controller, designed for fixed pitch electrically driven propellers, is based on a shaft speed control and employs an estimate of the propeller torque loss. A simulation study is performed in order to compare the presented approach wi...
