Task 7 H(s) U(s)- Hi(s) Y(s) Hz(s) The frequency response of a closed-loop feedback system is: H(s) H(s) = 1 + H (s)H(s) where H (s) is the frequency response of the system and H2(s) is the frequency response in the feedback loop. For: H}(s) = -35 H2(s) = k (where k is simply the k-times gain in the feedback loop, should be POSITIVE) Check: is the system H () stable? if it is NOT, is there a value of k for which the closed-loop feedback system H(s) becomes stable? For the calculations use sympy.
