1. An electric power generation controller for use in an aircraft,
the electric power generation controller being a controller of an electric power generating system configured such that: a manual transmission changes speed of rotational power of an aircraft engine; a continuously variable transmission changes the speed of the rotational power which has been changed in speed by the manual transmission; and the continuously variable transmission transmits the rotational power to an electric power generator,
the electric power generation controller comprising:
a manual transmission control section configured to, when a predetermined shift condition is satisfied, control the manual transmission to switch a gear stage of the manual transmission; and
a continuously variable transmission control section configured to, when the shift condition is satisfied, control the continuously variable transmission to such a side that fluctuation of an output rotational frequency of the manual transmission by the switching of the gear stage of the manual transmission is canceled, wherein
when the manual transmission performs shift-down to decrease a change gear ratio, the continuously variable transmission control section performs increase offset control of the continuously variable transmission to control an output rotational frequency of the continuously variable transmission to an increase side; and
when the manual transmission performs shift-up to increase the change gear ratio, the continuously variable transmission control section performs decrease offset control of the continuously variable transmission to control the output rotational frequency of the continuously variable transmission to a decrease side.
