Question

Solve the following Using MATLAB. (Please show the coding Script)

13. Solve Problem 13 Using MATLAB Given the unity feedback system of Figure P6.3 with G(S) = 5(56 – 233 - 5 + 253 + 432 – 85 - 4) tell how many closed-loop poles are located in the right half-plane, in the left half-plane, and on the jw-axis. (Section: 6.3) MATUA

Answer 1

%%% Matlab code

clc;
close all;
clear all;
format long;
G=tf([8],[1 -2 -1 2 4 -8 -4 0]);
F=1;
sys=feedback(G,F);
pzmap(sys);

OUTPUT:

Pole-Zero Map Imaginary Axis (seconds) -1.5 -1. 51 -0. 50 0.5 11.5 2. Real Axis (seconds)

From pole zero diagram

No. of closed loop poles in right half plan = 4

No. of closed loop poles in left half plan = 3

No. of closed loop poles on jw axis= 0
