Abstract
A control device for a rotary machine, which is driven by a turbine output torque which is an output of a turbine and an electric motor output torque which is an output of an induction motor, includes: a required output setting unit configured to set a required torque for driving the rotary machine; and a drive source command unit configured to set the electric motor output torque to a minimum torque or higher of the induction motor and to set the turbine output torque to a value obtained by subtracting the electric motor output torque from the required torque when the turbine output torque is greater than or equal to a lower limit in a stable output range of the turbine.
