A unit ramp input in the time domain is r(t)=t, and in the frequency domain it is R(s)=1/s^2. 1. Using Simulink, create a simulation model to demonstrate the analytical discussion. 2. Demonstrate the effect of a slight variation in omega_n and zeta. Explain the effect and why such variation would occur.
