Demonstrate for the second-order system (ωn = 100rad/s, ζ = 0.4) subjected to a step function input, U(t), that the damping ratio and natural frequency can be found from the logarithmic amplitude decay. Show that this is possible whether F(t) = KAU(t) with y(0) = 0 or F(t) = −KAU(t) with y(0) = KA. Use K = 1mV /mV and A = 600mV . Why would this technique be useful in practice?
