By employing MATLAB, perform the Bode plots of magnitude and phase of the control system in Example 4 of Section 11.8.1. The transfer function is
G(s)={\frac{20s^{2}+64s+35}{100s^{4}+503s^{3}+4021s^{2}+150s+240}}
The input to and output from MATLAB are included in Program Listing 11.10 and Figure 11E10.
Program Listing 11.10
>> num = [0 0 20 64 35];
>> den = [100 503 4021 150 240];
>> bode(num,den)
>> title(‘Bode Plot of a fourth order system’)
