A predictive header pressure controller uses predictive boiler steaming
models to anticipate future changes in boiler steaming rates, converts
the anticipated steaming rates to anticipated rates of change in header
pressure, compares the anticipated rates of change of header pressure to
measured rates of change of header pressure and controls header pressure
of a multi-boiler energy system to a derived rate of change header
pressure setpoint. The control may be accomplished by a control action
that is integral only or it may be an incremental output directly
compatible with distribution hubs. A control signal is directed to one or
more control devices that adjust and control header pressure.
