Abstract:
A control device for a supercharger of an engine, the supercharger comprising a mechanism for adjusting an intake air amount of the engine according to a signal, the device comprising:a sensor which detects a running state of the engine; a sensor which detects an intake air amount 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 intake air amount adjusting mechanism based on the target intake air amount; set an open loop control value of the signal based on the operational target value; calculate a feedback correction amount including an integral correction value of the signal to cause the intake air amount to coincide with the target intake air amount; calculate a learning value based on the integral correction value when the intake air amount coincides with the target intake air amount; modify the feedback correction amount to cause the sum of the learning value and the feedback correction amount to be constant; and output the signal determined based on the open loop control value, the learning value and a modified feedback correction amount to the intake air amount adjusting mechanism.
