# A process control system contains the following transfer functions: (a) Show how G O L (s) can be approximated by

## Question:

(a) Show how G_{O}_{L} (s) can be approximated by a FOPTD model;

Find K,Ï„, and Î¸ for the open-loop process transfer function.

(b) Use direct substitution and your FOPTD model to find the range of K_{c} values that will yield a stable closed-loop system. Check your value of K_{cm} for the full-order model using simulation.
