Learning control for engine test

Abstract

Abstract PURPOSE:To speed up the setting of the control level to a determined value by providing a learning operation control system to forecast changes in the subsequent operation level with respect to a specified set value from the relationship between the operation level up to the preceding time and the results of the detection of the control level corresponding thereto. CONSTITUTION:This invention is composed of a learning control system 1 comprising an air/fuel mixing ratio (A/F value) detector 11 for analyzing exhaust gas of the engine 3 and an operation level forecast controller 12 and a fuel feeder 2 comprising a pump motor 21, a carburetor 24 and the like. The pump motor 21 is operated through a forecast controller 12 by output of a setter 4 or a detector 11 to change the A/F value. Then, with the output of a detector 11, the operation level is forecast and set with the forecast controller 12 based on the results of the previous control, the actual operation level is changed by step until the control value detected meets the set value within an allowable range and then, held as it reaches the allowable range.
