Question: The plant transfer function for a particular process is G p (s) = 8 s / s 2 + 2s + 3. We wish

The plant transfer function for a particular process is G p (s) = 8 – s / s2 + 2s + 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 Kp for which the system is stable.

b. Determine the value of Kp required to give a time constant of t = 2/3.

c. Plot the unit step response of the plant for KP = I. A process containing a negative sign in the numerator of its transfer function is called a "reverse reaction" process. What is the effect of the negative sign in the numerator of Gp(s)?
