This paper describes robust sensorless induction motor control applied to electrical ship propulsion. The control fulfils the marine process specific requirements and constraints. The flux estimation is based on a two step adaptive Kalman filter (KF). A fourth order KF estimates the flux and the currents, then the rotational speed is estimated by integration of a nonlinear equation of estimated flux and current errors. Polynomial regulators (RST) are used in preference to the classical proportional/integral control for improved robustness and performance. (6 pages)
