This system is stable, since one of its zeros is in the
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

part of the s-plane
This system is stable, since its only pole is in the left-hand...
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
A
system has the transfer function H(s)=3(s2+7 s)/(s2+8s+4). Draw a
Bode plot of the transfer function and classify it as lowpass,
highpass, bandpass, or bandstop. Draw the Direct Form II for this
system.
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...
Used to determine the stability of a system by examining the
characteristic equation of the transfer function. States that the
number of roots of the characteristic equation with positive real
parts is equal to the number of changes of sign of the coefficients
in the first column of the array.
