right-hand part of the s-plane
This system is stable, since one of its poles is in the
right-hand part of the s-plane

Determine the transfer function H(s)/Q(s) for the liquid-level
system shown in Fig. Resistances R1
and R2 are linear. The flow rate from tank 3 is maintained constant
at b by means of a pump; i.e.,
the flow rate from tank 3 is independent of head h. The tanks are
noninteracting
Consider the transfer function G(s) = 1/[(s+1)^2(s+2)]. We use a
PI compensator C(s)=(as+b)/s and close the feedback loop.
1.) Find out the entire range of a and b at which the
closed-loop is stable and show it on the plane with a and b
axes.
2.) At the border of instability, find the frequency of
oscillations in terms of a.
3.) For what value of a, do we get the largest range of b for
stability? What is this largest...
