[[Attach:sp16.zip | Special Problem 16 Script Files]]

For Special Problem 16, Python 2.7 is required to run the simulations. It is available for free download from the [[http://www.python.org/getit/releases/2.7/ | Python web-site]]. To run the simulations, double-click on the appropriate python script. A web-page will open to allow you to view the solution.

!!! Lecture 41 - Distillation Control

A distillation column is typically a highly coupled system that leads to multiple interacting controllers. Techniques from this class that are useful for designing the control system are:
Empirical model fitting of a Multiple Input Multiple Output (MIMO) System
Relative Gain Array (RGA) analysis to determine best pairing of Manipulated and Controlled Variables
Simulate distillation column with PID Non-interacting controllers
Simulate distillation column with PID Interacting Controllers with Feedforward information from other controllers
Derivation of First Principles model
Nonlinear Control (NLC)

* %list list-page% [[Attach:Lecture41_notes.pdf | Lecture 41 Notes]]

The distillation column example uses both empirical and first principles approaches to address controller interaction. With the empirical approach, PID controller tuning is derived. With a first principles model, a nonlinear control can improve the disturbance rejection and set point tracking capabilities.
