PID tuning: is the devil as scary as he is painted? Part 5. Closed-Loop PID Autotuner

The concluding article in the series on Automated PID Tuning in Simulink, in which we look at the Closed-Loop PID Autotuner.

This block is similar to the previously discussed Frequency Response Based PID Tuner tool: it is also based on the harmonic analysis method. The block is located in the Simulink Control Design section of the Simulink library.
