Abstract
The amount of work of a work machine () is estimated using fuzzy logic based on the amount of operation of control units (L) to (L) which operate a hydraulic swing motor () and cylinders () to (). A setting signal, which sets the rotational speed of an engine () based on the estimated amount of work, is set using the fuzzy logic. The rotational speed of the engine () can be optimized according to the operator's operation intention with the control units (L) to (L), and energy loss of a hydraulic system can be suppressed.
