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.
