1. A process control element adapted to be used as a portion of a process control routine implemented on a processor to control a process that includes a set of process outputs effected by a set of process control input signals, the process control element comprising: a computer readable medium; and a control element stored on the computer readable medium and adapted to be executed on the processor to implement multiple-input/multiple output control of the process, the control element including; a first process model adapted to receive the set of process control input signals to produce a prediction signal for one of the process outputs; and a multiple-input/multiple-output control element adapted to receive an indication of the process outputs to develop a set of control signals, the multiple-input/multiple-output control element including a second process model adapted to develop a prediction vector for each of the process outputs and a correction unit adapted to modify the prediction vector for the one or more of the process outputs using the prediction signal for the one or more of the process outputs.
