PROBLEM TO BE SOLVED: To provide a control device for a gas turbine engine, in which if the engine is in a transient state including acceleration or in a stationary state is determined with favorable precision. SOLUTION: This control device for a gas turbine engine is provided with a first control system, taking inputs of values outputted from a group of sensors to control fuel supply to the engine based on all or part of the inputted values. The first control system takes inputs of the values outputted from the group of sensors, compares the change rate of the outputted values with predetermined threshold values respectively every prescribed time (change rate threshold value block 310a). When it is determined that the number of sensor outputs determined as exceeding the threshold values is more than prescribed, or more specifically, when it is 2 out of 4 values, or 3 out of 5 values, it is determined that the engine is in the transient state. When the number of times when it is determined as less than the prescribed threshold values is more than half, it is determined as the stationary state (determination block 310b).
