Control Loop Performance Monitoring in An Industrial
Setting. Edition No. 1
VDM Publishing House, Dec 2008, Pages: 100
The wide range of applications for single input
single output controllers have encouraged interest
in monitoring their performance. Over the past two
decades researchers in the area have found many
performance enhancement opportunities by applying
these techniques. These are most evident in large
operational plants with hundreds of controllers
being monitored at the same time. Early performance
measures were based on minimum variance control as a
benchmark for controller performance Many other
procedures have since emerged that have improved the
level of accuracy in these performance measures. In
addition, these improvements made it easier to
implement control loop performance monitoring in
large industrial settings. Performance indices that
address specific control objectives such as steady
state operations, set-point change, and disturbance
rejection were developed. Other indices focused on
addressing specific problems such as detection of
controller oscillation and control valve problems.
Furthermore, general performance settings for large
scale implementation were identified.
