Question

Use MATLAB to plot the Nyquist diagrams for each of the following systems. The MATLAB command is nyquist(gh), where gh represents the open-loop system transfer function G(s) H(s). R(s) + G(s) H(s) a. $G(s) = \frac{50}{s^2(s+1)}$ $H(s) = s + 4$ 20 $s+3$ b. $G(s) = \frac{20}{s(s+1)}$ $H(s) = \frac{s+3}{s+4}$ C(s)

Step 1

G(s) = s^2/(s+1) H(s) = 50/(s+4) First, we need to define the transfer function G(s) H(s) in MATLAB. We can do this using the tf() function: G = tf([1 0 0], [1 1]); H = tf([50], [1 4]); Show more…
