ABSTRACT:
A PID controller roughly controls several times of trial operations preceding an actual operation. A trial operation analyzing unit analyzes and learns the trial operations conducted under the control of the PID controller, thereby generating a criterial manipulated pattern that serves as a criterion of a time-series pattern of a manipulated variable in the actual operation. An actual operation controller controls the actual operation on the basis of the criterial manipulated pattern thus generated. An operation changeover switch changes over between the PID controller to the actual operation controller in accordance with the state of operation, i.e., the trial operation or actual operation. Thus, the control apparatus itself learns the trial operations, and can self-acquire the criterial manipulated pattern for the actual operation. That is, a suitable criterial manipulated pattern can be generated easily.
