Different but the Same

My blogs have a new home on the Control magazine website www.controlglobal.com. I have had a wonderful run here for the last 5 years with 230 posts. I came up with the name of this website¬†to show the importance and interrelationship of modeling and control. Jim Cahill and Deb Franke designed the website and got …

Batch vs. Continuous Control and Optimization – Part 3

Reactors are the pivotal unit operation that sets plant capacity and efficiency besides product quality. Reactors provide good examples of the common and distinctive opportunities for the PID control of batch, fed-batch, and continuous unit operations. Here we examine pressure, temperature, and endpoint control. The pressure control of batch, fed-batch, and continuous reactors may have …

Batch vs. Continuous Control and Optimization – Part 2

Batch and continuous temperature loops can have vastly different responses. Fortunately, temperature loops have a characteristic early in the response that enables a fast identification of the process dynamics. The resulting models can be used for process control improvement, tuning, and rapid deployment of models for plantwide simulations. Temperature is the most important common measurement …

Batch vs. Continuous Control and Optimization – Part 1

Feedback control systems play an important role in batch and continuous unit operations. What are the similarities and differences in the process response, tuning, control strategies, and advanced process control opportunities? What can continuous control specialists learn from batch control experts and vice versa? Is it possible there are some fundamental principles unifying our solutions …
