Abstract

PURPOSE:To have a quick response to an unexpected fluctuation of load, by setting the lowering of engine rotation if any at the amount of control and then deciding the feedback as the control amount by the sum of the proportional control component, the integral control component and the basic control amount using the water temperature for the variable/constant. CONSTITUTION:When the measured rotational frequency N of an engine becomes less than the target rotation a frequency Nset, the deviation DELTAN is calculated by the subtractor 28. Then the Ipo memory table 29 is provided to the deviation DELTAN to store the 1st control signal Ipo. The proportional part is presumed according to the lowered amount of the frequency N and then stored in the memory table 22, and the 2nd control signal extracted out of the table 22 is reduced down to zero by the comparator 30 and as the time elapses. After a comparison 30, the engine is controlled by the 2nd control signal. Thus the lowered amount of rotation is set at the control amount, and the feedback is decided to the control amount from the sum of the proportional control component, the integral control component and the basic control amount using the temperature as the variable/constant. As a result, a quick response is secured to an unexpected fluctuation of load.
