The plant transfer function for a particular process is G p (s) = 26 + s

Question:

The plant transfer function for a particular process is

G_p(s) = 26 + s – 2s² / s(s + 2) (s + 3)

We wish to investigate the use of proportional control action with this plant.

a. Obtain the root locus and determine the range of values of the proportional gain K_p for which the system is stable.

b. Determine the value of K_p required to give z = 1.

c. Plot the unit step response of the plant. What is the effect of the negative sign in the numerator of G_p(s)?
