    Abstract

    The engine idle speed state becomes unstable as one drives a vehicle for several years. The purpose of this paper is to study on the control of the engine idle speed under sudden loads which are severe disturbances on engine. Three types of the closed-loop controller are developed for the stable engine idle speed control. The input of the controller is an error of rpm. The output of the controller is an IACV duty cycle. The anticipation delay is considered to deal with the delay time of the air mass in engine. The experimental results are obtained by the real time controller board. The controllers with the anticipation delay have improved the engine idle speed condition more than the current ECU map table under the loads.
