Real time implementation of robust controller based tuning for desired closed-loop response for SI/SO systems [articol]

Abstract

In this article, the IMC-PID approach is generalized to obtain the PID parameters for general models by approximating the ideal controller with a Maclaurin series in the Laplace variable. It turns out that the PID parameters so obtained provide some what better closed-loop responses than those obtained by PID controller tuned by other methods. Further all of the PID parameters depend on the desired closedloop time constant in a manner consistent with engineering intuition. The effectiveness of the PID controllers tuned by the proposed tuning method will be validated both by simulation studies and real time implementation.
