Abstract
PURPOSE: To provide a forecasting controller which is effective to a process with large delay by constituting same such that a value of a desired value setting means is operated by a forecasting control circuit which includes an arithmetic expression model section adapted to approximate conducts of the object of control and a feedback loop of variables of the arithmetic expression model.
CONSTITUTION: A modifying value r is added to an output of a desired value setting means 1 to obtain a desired value. The deviation 5 of an output 4 of an object 3 of control from the desired value is applied to a PID controller 6 which outputs an operating amount 7 to the control object 3. In order to decrease influences from disturbances 8 applied to the control object 3, a model 11 to approximate conducts of a control amount over the distrubances and another model 14 to approximate conducts of a control amount over fluctuations of the desired value are provided. The desired value modifying amount r obtained from outputs of those models 11, 14 and their differentiated outputs is applied to the desired value setting means 1.
