A method for verifying actuator control data includes a first operation of transmitting, by a host computer, a plant model to a simulator for verifying actuator control data, a second operation of transmitting, to an engine controller connected to an actuator, an engine simulation information signal of the plant model that is received from the simulator, a third operation of driving, through the engine controller, the actuator according to the engine simulation information signal, receiving, by the engine controller, a feedback signal transmitted from the actuator, transmitting the feedback signal to the host computer, and measuring control data, and a fourth operation of comparing the control data with target control data preset in the host computer and verifying whether the control data is abnormal.
