Abstract
An exhaust gas recirculation control system which is adapted to control the valve opening of the exhaust gas recirculation valve so as to minimize the difference between a detected value of the valve opening of the above value and a command value determined as a function of operating conditions of the engine. The valve opening is corrected at a higher speed when the above difference has a larger absolute value, and at a lower speed when the difference has a smaller absolute value, to ensure prompt and accurate control of the exhaust gas recirculation quantity.
