Abstract
A control apparatus of a supercharging system for supplying an engine with compressed intake air, includes: a supercharger including a compressor configured to compress the intake air to be supplied to the engine; and a controller for controlling a control device affecting operation of the compressor. The controller includes: a compressor map storage part configured to store a compressor map which indicates a relationship of an intake volume flow rate, a pressure ratio, and a compressor rotation speed in the compressor; a current position calculation part configured to calculate a current position of an operational point of the compressor on the compressor map every predetermined period; a moving direction calculation part configured to calculate a moving direction of the operational point on the compressor map on the basis of the current position of the operational point calculated by the current position calculation part; and a control part configured to control the control device on the basis of the current position of the operational point calculated by the current position calculation part and the moving direction of the operational point calculated by the moving direction calculation part.
