2. Automatic control of marine propellers

To regulate a propeller's speed Ω or propulsion power, it is necessary, even summarily, to have a mathematical representation. The representation of the torque C _r of a propeller is often of the form C _r = kΩ ² , in a more general way, k being a function of navigation conditions ( [D 5 610] , § 1).

When considering the inertia involved in servoing, we need to take into account the overall inertia, including the motor itself, the shaft and the propeller...
