Abstract
A control system for general-purpose spark-ignition internal combustion engine to be used for a portable generator, etc., having one or two cylinders and an actuator connected to the throttle valve to open or close the throttle value. In the system, an adaptive controller with a parameter identification mechanism is provided which receives a detected engine speed and a desired engine speed as inputs, and computes a command value to be supplied to the actuator, using an adaptive parameter identified by the parameter identification mechanism, such that the detected engine speed is brought to the desired speed. In the system, the desired engine speed is determined such that the desired engine speed per unit time is not greater than a prescribed value and the command value is determined to be within the upper and lower limits of the throttle value.
