Question
A common application of control systems is in regulating the temperature of a chemical
process The flow of a chemical reactant to a process is controlled by an actuator and
valve. The reactant causes the temperature in the vat to change. This temperature is
sensed and compared to a desired set-point temperature in a closed loop, where the flow
of reactant is adjusted to yield the desired temperature. The transfer function of the
system is as shown below:
(b)
s(s+3)
s3 + 5s? + 4s + 20
By using s-plane plot, show either the system is stable, marginally stable or unstable.
G(s) =
