Adjusting the Coefficients of the PI^α D^β Controllers Using Iterative Feedback Tuning (IFT) Algorithm

Mohammad Ali Vali; Mahdi Mashayekhi Esfichar; Shahriar Farahmand Rad

Volume 5, Issue 2 , July 2020, Pages 39-64

https://doi.org/10.30473/coam.2021.56679.1156

Abstract
  Iterative feedback tuning (IFT) is an algorithm for adjusting the coefficients of the integer-order type proportional-integral-derivative (PID) controllers without needing a system model‎. ‎The IFT algorithm is performed iteratively with the aim of optimizing the control coefficients at each ...  Read More
