#3: For G(s) below, find the gain crossover frequency (wg), the phase crossover frequency (wp). the gain margin and the phase margin using the four methods listed below (Note H (s) is assumed equal to 1). For a, b, and c, write on the graph where all four requested answers are (Gain Margin, Phase Margin, wg, and wp). 2 (8 +1) (s2 + 28 +1) a) Use a straight line Bode Plot approximation. Neatly, indicate where all four requested parameters are on the graph. (5 pts) b) Use a Nichols plot run in Python. Include all the Python commands you used and include the plot. By hand, neatly indicate where all four requested parameters are on the graph. (5 pts) c) Use a Python bode plot. Include all the Python commands you used and the graph. By hand, neatly indicate where all four requested parameters are on the graph. (5 pts) d) Use the Python margin command and simply record the results on your paper.
