ABSTRACT:
A control system for controlling an actuator which controls operation of an internal combustion engine in compliance with a target value varying continuously depending on the operation condition of the engine. The control system comprises: means for detecting the operation condition of the engine; processor means for calculating and setting a target value depending on the operation condition of the engine; detector means for detecting the up-to-date value of the actuator; discriminator means for discriminating a difference between the target value and the up-to-date value to supply an output signal for controlling the actuator; a driver for energizing the actuator in response to the output signal from the discriminator means; and a counter means for counting the recurring times of the up-to-date value deviating from an allowable range which has been set to span a constant width while taking the target value as a central value, the counter means generating a signal for stopping the actuator when the recurring number counted thereby reaches a pre-set number so that the actuator is stopped tentatively for a predetermined period.
