2. Matlab Program to plot Bode and Root Locus plot for the given transfer function
o suppose we have the transfer function as     s s^2 + s + 4 Then the Matlab program for the bode plot will be as follows: clc clear all num=[1, 12]; den=[2, 1, 4]; system=tf(num,den) bode(system)

4. Plot the root-locus of the following system
Plot the root-locus of the following system. h = tf([2 5 1],[1 2 3]); rlocus(h)

6. nyquist(sys) nyquist(sys,w) nyquist(sys1,sys2,
nyquist(sys) nyquist(sys,w) nyquist(sys1,sys2,...,sysN) nyquist(sys1,sys2,...,sysN,w) nyquist(sys1,'PlotStyle1',...,sysN,'PlotStyleN') [re,im,w] = nyquist(sys) [re,im] = nyquist(sys,w) [re,im,w,sdre,sdim] = nyquist(sys)

7. Plot the Nyquist response of the system
H = tf([2 5 1],[1 2 3]); nyquist(H)

9. Time Responses For illustration purposes, create the following third-order transfer function: sys = tf([ ],[ ]) subplot(2,1,1) step(sys) subplot(2,1,2) impulse(sys)

11. Frequency Response
sys = tf([ ],[ ])

12. bode(sys) grid

13. nyquist(sys) grid

14. nichols(sys) grid

15. rlocus(G) grid
