This manuscript presents an extension of the IMC-PID tuning method. A higher-order structure is adopted for the process model than in the original method, where a FOPDT (First-order Plus Dead Time) model is used. Then, the general IMC procedure is applied, and the so obtained regulator is approximated with a (real) PID. Simulations and experimental results indicate that abandoning the FOPDT structure in the IMC approach is beneficial both in terms of performance and robustness.

Abstract
This manuscript presents an extension of the IMC-PID tuning method. A higher-order structure is adopted for the process model than in the original method, where a FOPDT (First-order Plus Dead Time) model is used. Then, the general IMC procedure is applied, and the so obtained regulator is approximated with a (real) PID. Simulations and experimental results indicate that abandoning the FOPDT structure in the IMC approach is beneficial both in terms of performance and robustness.File in questo prodotto:
