1. A compressor control device, comprising:
an inlet guide vane disposed in an inlet section of a compressor;
a variable stationary blade disposed downstream of the inlet guide vane;
a rotor blade disposed between the inlet guide vane and the variable stationary blade;
a first actuator for adjusting a first opening degree of the inlet guide vane;
a second actuator for adjusting a second opening degree of the variable stationary blade;
a compressor inlet temperature detection part for detecting a compressor inlet temperature in the inlet section; and
a control part for controlling the first actuator and the second actuator,
wherein the control part controls the first actuator and the second actuator such that an opening degree ratio of the first opening degree to the second opening degree increases as the compressor inlet temperature decreases, when the compressor inlet temperature is less than a threshold, and
wherein the control part controls the first actuator and the second actuator such that a second change rate of the second opening degree with respect to the compressor inlet temperature is greater than a first change rate of the first opening degree with respect to the compressor inlet temperature, when the compressor inlet temperature is less than the threshold.
