A feedback system is shown in the following figure Use Nyquist Criterion to determine the range of k that can make the system response stable. Discussion: if it is required that the system Maximum overshoot needs to be lower than 15%, would it be able to determine the k range without Bode diagram? if so, please briefly explain the general procedure of how you plan to find out k range; if not, please explain why. ( do not need to calculate for it, just explain the general procedure, or why it does not work)
please give me the step response gain margin, phase margin and bode plots using octave

Find the equivalent transfer function of the negative feedback system of figure below: R(s) C(s) G(s) H(s) G(s) K and H(s) =1 s(s +2)? find two values of gain that will yield closed-loop, overdamped, second-order poles. Repeat for underdamped poles find the value of gain, K, that will make the system critically damped. find the value of gain, K, that will make the system marginally stable. Also, find the frequency of oscillation at that value of K that makes the system marginally stable.

Below is a very common feedback block system. It is a 1dof, and unity-feedback system. The input is the reference command R(s). This is what flows out of thin air, into the system. All other signals in the system (e.g. U, Y, etc.) will depend on R(s). R(s) a. E(s) e. K U(s) G Y(s) Write the algebraic relation between the output Y(s) and the reference R(s) in terms of G and K?. Write it in the format Y = some function of s * R b. What is the TF from R to Y, aka the closed loop TF? What is the "Loop TF" aka the "the open-loop TF"? G has zeros at ZG1, ZG2 etc. and poles at PG1, PG2 etc. C. K has zeros at ZK1, ZK2 etc. and poles at PK1, PK2 etc. What are the zeros and the poles of OLTF? What are the zeros and the poles of CLTF? d. Write the algebraic relation between the error E(s)=R-Y and the reference R(s) in terms of G and K? Write it in the format E = some function of s * R.

If the system is to be arranged in a closed-loop, with a controller gain K in the forward path and a unity negative feedback loop, what is the maximum value of K which could be used without the system becoming unstable? Assuming you use Figure Q5 for this, use a sketch to show how you obtained the values from the plot.
