2.13 Coupling Data Reconciliation with Process Control and
Optimization

As discussed in Chapter 2 introduction, data reconciliation has off-line applications
such as process audit, metallurgical inventories, process modeling, plant design or
reconfiguration, and tuning of operating conditions. Applications of on-line data
reconciliation to automatic control and real-time optimization have also an inter-
esting potential in process engineering, since, as in off-line applications, the use
of better information would improve the performance of the methods that requires
experimental data [47, 48, 121, 122]. Figure 2.25 gives a general scheme of the in-
tegration of a data reconciliation procedure into process control and optimization
loops.
