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?

Not all second-order systems are designed to give a standard 2"d order response. Consider the power steering for an automobile. The feedback system can be modeled as the block diagram shown in the figure below. For a unit step input A(s), find values of K1 and K2 for which the response w(t) is critically damped and has a steady-state gain of 0.4 unit. Repeat for a damping ratio of 0.7 and a steady-state gain of 0.2 unit. 7) Control Steering...
