Multi-loop systems block reduction techniques
Do I start by multiplying 18/s+3 * 1/s+3 = 18/(s+3)^(2)?
Then is it (18/(s+3)^(2))/(1+(18/(s+3)^(2)*4)) = 18 / ((s + 3)^2 * (72 / (s + 3)^2 + 1))?

Estimation of bode plot of closed loop system based on open loop characteristics [closed]
I just got an exam back in which I did the error of not drawing the phase part of the bode plot of a closed loop system. The question sparked, how does one estimate the shape of the phase plot of a ...

Bode phase plot phase margin
From what I have studied so far, gain margin is defined as how much additional gain the system can be given before it becomes unstable, and this can be measured from the bode magnitude plot ...

what is the open and closed loop function of this system?
i found this in the text book.
i solved by:
1- found the closed loop function of just the part of B(p) and its "feedback", let's call it B'(p).
2- after that i did H(p) = A(p) / ( 1 + A(p) * ...

Confusion regarding finding closed loop transfer function and damping constant from open-loop transfer function
I have second order transfer function $$ G(s) = \frac{1.247}{s^2+9.76s+23.8}$$ G(s) is in the forward path of a unity feedback system.
How do I find the closed loop transfer function and damping ...
