METHOD AND DEVICE FOR CONTROLLING SPEED OF ENGINE GENERATOR

摘要

PURPOSE:To minimize the coefficient of instantaneous load fluctuation for simplifying the composition of a control device by computing control input taking a signal formed by adding a load differential signal to a speed deviation signal for a deviation signal, and then correcting the quantity of fuel supply on said control input. CONSTITUTION:A differentiator 5 differentiates the output of a load detector 4 to output a differential signal LD. A deviation signal generating circuit B is supplied with the output signal LD of said differentiator 5, the output signal NO of a speed setting equipment 6 and the output signal N of a speed detector 7 as its input to issue the deviation signal. PID computing circuit 9 is supplied with said deviation signal as its input to compute control input. A fuel injection pump 11 supplys fuel to a diesel engine 2. Thus the coefficient of instantaneous load fluctuation can be minimized to simplify the composition of a control device.
