Abstract:
A control device for a turbocharger of an engine, the turbocharger comprising an actuator which adjusts an intake air amount of the engine according to a command signal, the control device comprising:a sensor which detects a running state of the engine; and a controller functioning to: set a target intake air amount of the engine based on the running state; calculate an operational target value of the actuator based on the target intake air amount; calculate a first compensation value of a response delay from operation of the actuator to variation of the intake air amount; calculate a second compensation value of an operating delay of the actuator with respect to an input of the command signal to the actuator; calculate the command signal by performing a processing based on the first compensation value and the second compensation value on the operational target value; and output the command signal to the actuator.
