A process control system contains the following

(a) Show how GOL(s) can be approximated by a FOPTD model;

Find K, τ, and θ for the open-loop process transfer function

(b) Use Routh stability methods and your FOPTD model to find the range of Kc values that will yield a stable closed-loop system. Repeat for the full-order model using MATLAB.

(c) Determine and the corresponding w.
