ELECTRIC PROPULSION SYSTEM CONTROL APPARATUS

摘要

The present invention provides an electric propulsion system control apparatus that uses electric means alone so that effects pertaining to weight and cost are suppressed, is capable of accurate detection even when an airspeed has a binary relationship with a torque and a rotation speed of a propeller, and thereby exhibits improved detection precision and responsiveness. The electric propulsion system control apparatus drives a propulsion propeller to rotate, and is configured to estimate the airspeed from a data set stored in advance in relation to the airspeed and a propeller characteristic, and a plurality of torque and rotation speed estimation values detected under different driving conditions.
