In Matlab please do this problem and show the code.

(Figure 3.2 is 2.2)

Use Figure 2.2 to create a transfer function representing an armature-controlled DC motor system. Figlre 3.2: Armature-Controllf DC Motor System Use the given system parameters of J=0.2(kgm2),b=10(Nm/(rad/s)),Ka=Kb=0.45,Ra=6(), and La=10(mH) to determine the voltage-speed transfer function. Plot the response of the system when it is subjected to an armature voltage step from 2 (V) to 3(V) at t=0
