APM.PRED_HOR - APMonitor Option

Global Options | Local Options
 Type: Integer, Input or Output (with CSV read)
 Default Value: 1.0
 Description: Prediction horizon
              Total horizon, including control horizon

PRED_HOR is the prediction horizon that includes the control horizon and any additional points to track towards steady state. The PRED_HOR must be greater than or equal to CTRL_HOR (control horizon). As opposed to CTRL_HOR, no manipulated variable movement is allowed in the prediction horizon. The individual size of time steps of the prediction horizon beyond the control horizon are set with PRED_TIME. The PRED_TIME is generally larger than the CTRL_TIME to give a section of the overall horizon that predicts steady state arrival to the set point. When CSV_READ is on and the horizon time points are specified from the data file, the CTRL_HOR and PRED_HOR are set equal to the number of time steps present in the data file.
