In his latest article, Nick Cross explores an interlock monitoring solution which provides an intuitive display of dynamic interlock visualization that mirrors the interlock configuration on the Integrated Control and Safety System (ICSS). Through real-time monitoring and analysis of the interlock data, this software tool can help to reduce production delays and improve operations.

Pretest and PID tuning is a common and general activity in APC projects. This is a story about how these common activities diagnosed a larger problem at a well-known NGL facility.
Read moreThe Role of Feedforward in Process Control
The design of the feedforward controller takes time and requires knowledge of the process and disturbance dynamics. Therefore, the decision of whether to implement or not to implement feedforward is a tradeoff. For this reason, it is interesting to have a quantitative index measuring the performance improvement that can be obtained by adding a feedforward compensator.
