QUESTION 16 5 points Save Answer Consider a unity negative feedback control system. It is assumed that the plant G(s) includes an integrator and you are using a proportional compensator K. You want to increase the closed-loop ramp tracking performance. Currently, the steady-state tracking error of the closed-loop system with KK old to a unit ramp signal is 0.1. You would like this error to be reduced to 0.025 with a new proportional compensator K=K_new. How does the proportional gain have to change to make this possible? We assume that the closed-loop is stable for all values of the proportional gain K_new = 4.33 K_old K_new = 4 K_old K_new = 0.25K_old K_new = 5.44 K_old = QUESTION 17 5 points Save Answer Given that G(s) = 2.1({+10)(8-5)>(s(s+6)(5+7)). calculate the phase of G(w) in radians for a frequency Provide your answer with two decimal precision of 7 rad/s
