ABSTRACT:
A command value decision unit capable of solving a problem of a conventional system in that when using a static fuel consuming characteristic model obtained by the least squares method as a fuel consuming characteristic model, it is sometimes difficult to decide the output command value P.sub.m * of each plant at high accuracy owing to the deviation of collected data and the response delay of the plants. The command value decision unit generates an output decision model of each plant by extracting items that affect the fuel consumption at the present time from among the items of the fuel consuming characteristic model of each plant, which is formed by taking account of hysteresis characteristics of the plant, and decides the output command value of the plant on the basis of the output decision model.
