Test of a PI digital controller with Automatic Tuning

Information

Description

In this example have been tested the functionalities of the digital PI with Automatic Tuning.
The PI has to control the process with transfer function

   Y(s)           1
   ----  =  --------------
   U(s)       (s + 1)^3
  
There are three PIs that are automatically tuned. The PIs have different Phase Margin requirements: 45, 60 and 70 respectively.
The first image shows the process variables controlled by the three PIs PV.

There are thre phases:

Control signals
