Respected sir

i am currently doing phd work on fractional order pid controller design for drilling machine which has a transfer function
1958/s^3 + 17.89s^2 + 103.3^s + 190.8
how i will design the fopid controller for the above transfer function of the order 3
when the above model should be approximated by a first order lag plus time delay system which is give in the following
G = (10/1+.387*s)*e^-197*s
how i will combine the fopid controller and above transfer function to get combined transfer function
basically i am going to design various controller stratgies for FOPID using soft computing techniques.
please suggest
thanking you
