### Lecture 40 - Controller Interaction

Controller interaction can lead to undesirable closed-loop characters. Controllers that "fight each other" can cause persistent oscillations or even instability. The purpose of this lecture is understand the root of controller interactions and propose methods to alleviate problems.

The distillation column example uses both empirical and first principles approaches to address controller interaction. The first sheet is a derivation of the empirical model while the second sheet is a derivation using first principles.

#### Homework

1. Course reading for next class: Review course material
2. Assignment due by the start of Lecture #42: SP16

Relate each problem in the context of the overall course objectives.
