PID tuning: is the devil as scary as he is painted? Part 3. Response Optimizer

In this article, we'll walk you through the process of tuning a controller for a nonlinear drive model using the Response Optimizer tool.

Until now, we have considered only linear systems ( part 1 and part 2 ). They are needed to understand the principle of operation of a real (nonlinear) system and a rough definition of its characteristics. However, in practice, one has to deal with a nonlinear model.
