Second Order Transfer Functions and PID Control Loop Tuning

Second order transfer functions are not very common in chemical plants and oil refineries but they do exist and make up about 5% of all control loops. About 70% of all industrial processes can be characterized by first order transfer functions, 20% by zero order transfer functions and the remaining 10% can be characterized by […]

Troubleshoot MPC Models And Improve MPC Performance Using New Technology Not Needing Step Tests

You and your team worked hard for six months, completed an MPC project successfully. A few months later, many CVs (controlled variables) are oscillatory and looks like below: You do not have the time and resources to find out what is the cause of the oscillations. You can auto-step tests (auto-step program) from Aspen DMC3 […]
