A target value processing unit, includes: an input section to which a
target value signal showing a target value of a control process is
inputted; a target value shaping unit shaping the target value signal
inputted to the input section, into a signal form which is proper for a
control treatment of a regulator implementing the control process; and an
output section outputting to the regulator a shaped target value signal
which is shaped by the target value shaping unit. The target value
processing unit realizes the high-level control process without improving
the regulator.
