Title:
ENGINE ROTATIONAL SPEED CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/164946
Kind Code:
A1
Abstract:
An engine rotational speed control apparatus (4) is provided with a noise elimination process unit (6) for correcting a command value. The noise elimination process unit (6) is configured to set a current first output value (B(i)) to be the same as a previous first output value (B(i-1)) when, in the most-recent group of steps, the number of successive increased steps is smaller than a first predetermined number (n) and the number of successive decreased steps is smaller than the first predetermined number (n). An increased step is a step with a current first input value (A(i)) greater than a previous first output value (B(i-1)) by a first setting width (n) or more. A decreased step is a step with the current first input value (A(i)) smaller than the previous first output value (B(i)) by the first setting width (n) or more.
