* if possible, kindly the solution isnt handwriting ( text through keyboard ) is much appreciated and readable*

Course:

EE 350 ( System Dynamics and control ) Major: electrical engineering

Note: Bartleby expert solved first TWO three sub-parts A,B,C,D,E and F. and told me to post the question again so the rest of the solution could be solved ( G, H ).

Considering the root-locus given, which is plotted for a unity feedback system for K > 0,
(a) Obtain the open-loop transfer function.
(b) Obtain the closed-loop transfer function.
(c) Find the value of gain and closed-loop poles at the
imaginary axis crossings.
(d) Write the range of K for which the closed loop
system is stable.
(e) Write the value of gain that makes the system
marginally stable.
() What would be the period of oscillation in seconds
when the system is marginally stable?
(g) What would be the settling time, peak time and
percent overshoot at the gain of K = 15?
Method: For K = 15, the closed-loop poles appear
at -7.36, –0.82 + j1.81. Show if the 2nd order
approximation is valid. Then use the formula given
at the footer.
