Human Factors Aspects of Advanced Process Control
Abstract
Energy conservation practices, such as heat recovery and
integration, require that many chemical and related processes
use advanced control systems.
Many of the more advanced process control strategies and
algorithms can cause operator confusion, leading to incorrect
operator actions and negating the advantages of the advanced
control. If the operator makes a mistake and upsets the process,
or fails to respond correctly to a process upset, the loss can
exceed the possible savings of the advanced control. Further,
the experience can result in the operator not using the control
capability in the future.
Display and man/machine interface techniques, based on an
understanding of human factors and of an operator's typical
analysis of a process, can be used to present information to the
operator in a manner which will prevent confusion. This paper
discusses techniques for selecting and displaying process and
control information to the operator.
