###### Question details

Draw the Nyquist diagram of the open-loop transfer function shown in Equation .

Clearly show the real and imaginary axis intercept points and the high frequency asymptote. (10 pts.)

(b) From the Nyquist diagram, can you determine if there a range of controller gains that will make this system stable? Explain and write the critical gain if available. (6 pts.)

(c) Draw a generic Nyquist plot and show the gain margin and phase margin on the plot. (4 pts.)

KG(s) = K/(s + 2)(s − 1)
