For the problem above: 1. Plot in MATLAB the output-input ratio, |G(iw), and phase lag, 4, as a function of fre- quency on two separate plots over the range of input frequencies w from 0 to 30 rad/s. • You may use either (a) your analytical results for |G(iw)| and & from Problem 4, or (b) your analytical expression for G(iw) along with additional MATLAB commands (e.g., angle, abs, real, imag, atan2) to compute |G(iw)] and ø. • The curve of should be plotted in degrees and vary smoothly from 0 deg towards -180 deg. • To receive credit for this problem you cannot use other MATLAB-based tools that automatically generate the frequency response (we will discuss tools such as bode later on). 2. Based on your plot, at what frequency does the system resonate? What is the approximate phase lag at this point? 3. Indicate on your plot (either by hand, or by plotting a marker in MATLAB) the two values (w, G(iw)) and (w,p) from Problem 1 (if both problems are completed correctly this pair of points should fall on the frequency response curve plotted in MATLAB).
