MATLAB exercise - Control System Toolbox functions for Linear (time-invariant) systems: Reference: section 4.9 and 5.7 of textbook or MATLAB help - Use the functions from Control System Toolbox in MATLAB to solve the following problems Consider the following linear system + 2x + 225x-f(t) Part A) Time-domain analysis A1) Define the system in the transfer function form using tf function (Page 254) A.2) Using Isim function (Page 254), plot the forced response of the system (in one plot) for the following harmonic forces. Compare the amplitude of response and justify your observations A.2.1) fi(t)-1* sin(10*t) A.2.2) f(t) = 1 * sin( 14.94) A.2.3) f(t)-1* sin(30*t) Note: plot the response for the first 10 seconds (0 t
