Performance analysis of robust stable PID controllers using dominant pole placement for SOPTD process models

作者:

Highlights:

• Dominant pole placement tuning of PID controllers is proposed for SOPTD processes.

• Analytical expressions are derived considering 3 closed loop non-dominant pole type.

• Third order Pade approximation is used to handle the time delay terms.

• Robust stable solution of PID controller are achieved using k-means clustering.

• Different time and frequency domain performances are shown for 9 test-bench plants.
