Question

Required information Use MATLAB to create a state-variable model and obtain the expressions for the matrices A, B, C, and D. Choose the correct transfer functions of the following models for the given inputs and outputs. -6a1 + 782 + 4u 2 = x1 - 522 + 3u2 The output is xy: the inputs are u and u2.

Answer 1

Answer will be 2nd option.

The ean in matrix form -6 7 lat -5 output y is in terms of 2483 ý = [10] ct [o of u Now, ć=AxtBu y=(xt Du A = [4 75 B=100 c = [1 o3 Now, using MATLAB

MATLAB code:

A=[-6,7;1,-5];
B=[4,0;0,3];
C=[1,0];
D=[0,0];
sys=ss(A,B,C,D);
ans=tf(sys)
