Use MATLAB to break down the transfer function into its partial fractions and draw the block diagram consisting of the partial fractions in parallel. To find the partial fractions: Syst pt - part fra ) b. Find unit step response of each partial fraction and plot individually in a single figure by MATLAB for OSES 15 sec. Also, plot the sum of these responses to find the unit step response of the original system. You may use the following MATLAB commands in an m file, assuming G1,G2, G3, G4 are partial fractions of Gs): figure hold Yls -(1/ yit - Slaplace (1) Tplot tyit, 10.15)) Y2 - (1/5) 02 y2t - Alaplace(Y2) fplot tyt, 10.15)) de plots of retaining partial fractions. finally do the sum of above responses Ya - (1/a) (G1G2G3G4) yt - Ilaplace(a) plot tyt, 10.15) hold Release the hold on plots. axis ([0,15,-.6, +.6) Set axes rangest Oct 15 -0.6 .0.5. grid minor legend stand, th'.
