This paper deals with the problem of the control of thrust generated by conventional bladed propeller of marine thrusters and moved by an electric motor. This paper described a control law based on the estimation of the thrust using two features: an extended Kalman filter to observe the torque and an reversed hydrodynamic model of the propeller to control the thrust by a proportional-integral controller. The performances and robustness of this control law is compared to a PI controller without estimator and to the model-based-velocity control.
