A Unity feedback system has an open loop transfer function
of
G(s) = K / s (s+1) (s+5)
Draw the root locus plot and determine the value of K to give a
damping ratio of 0.3 A network having a transfer function of 10(1
+10s) /(1 +100s) is now introduced in tandem. Find the new value of
K, which gives the same damping ratio for the closed -loop
response. Compare the velocity error constant and settling time of
the original...

Q2. Determine and plot the frequency response function H(e^jw)
(magnitude and phase normalized in w). Choose n = [-20, 20].
1. h(n) = (0.9)^│n│
2. h(n) = [ (0.5)^n + (0.4)^n] u(n)

Consider the unity feedback negative system with an open-loop
function G(s)= K (s^2+10s+24)/(s^2+3s+2).
a. Plot the locations of open-loop poles with X and zeros with O
on an s-plane.
b. Find the number of segments in the root locus diagram based
on the number of poles and zeros.
c. The breakaway point (the point at which the two real poles
meet and diverge to become complex conjugates) occurs when K =
0.02276. Show that the closed-loop system has repeated poles...
Sketch the wave-function of the ground state of a particle of
mass m which is con- fined in one dimension within a square
potential well of infinite height, centred at x = 0 and of width a
between x = ?a/2 and x = a/2.
What type of function is that?
If the infinite potential well is replaced by a potential well
of finite height, sketch the new ground state
wave-function. Explain qualitatively how the
ground state energy changes in...
