Abstract:
A control system for a throttle valve actuating device including a throttle valve of an internal combustion engine and actuating means for actuating said throttle valve,said control system including, predicting means for predicting a future throttle valve opening and controlling said throttle actuating device according to the throttle valve opening predicted by said predicting means so that the throttle valve opening coincides with a target opening, wherein said throttle valve actuating device is modeled to a controlled object model which includes a dead time element, and said predicting means predicts a throttle valve opening after the elapse of a dead time due to said dead time element, based on said controlled object model; and identifying means for identifying at least one model parameter of said controlled object model, wherein said predicting means predicts the throttle valve opening using the at least one model parameter identified by said identifying means.
