Abstract

A state control apparatus includes a calculator for calculating adjustment amounts for adjusting a plurality of end effecting devices on the basis of preset values and measured amounts measured by a plurality of meters. The measured amounts indicate respective states of the end effecting devices. The adjustment amounts are required for conforming the measured amounts to the preset values, respectively. The state control apparatus further includes a parameter generator for generating a plurality of parameters on the basis of settings by a user. The state control apparatus further includes a comprehensive controller for outputting activating signals for activating the respective end effecting devices based on the respective adjustment amounts and the plurality of parameters. When the comprehensive controller outputs one of the activating signals for activating one of the end effecting devices, the comprehensive controller does not output the other activating signals for activating the other end effecting devices.
