1. An aircraft control system comprising:
a first engine that is attached to an airframe of an aircraft;
a second engine that is attached to the airframe of the aircraft;
a first power generator that is connected to an engine shaft of the first engine;
a second power generator that is connected to an engine shaft of the second engine;
an electric motor that is driven with electric power supplied from one or both of the first power generator and the second power generator;
a rotor that is driven with a driving force output from the electric motor; and
a controller configured to:
estimate whether noise excess conditions of the first engine have been satisfied on the basis of information for estimating noise of the first engine, and
based on the noise excess conditions of the first engine being satisfied and based on a fuel efficiency reference, change one or both of a rotation speed of the first engine and a magnitude of a torque of the first engine such that noise of the first engine is lower than the noise excess conditions.
