Example that demonstrates the use of the PID controller
with hysteresis. The control objective is to keep
the temperature of the energy storage cap
at 40°C.
The controller con
is parameterized to
switch on if the control error is bigger than
eon=1.
The output of the controller remains above ymin=0.3 until the control
error is smaller than eoff=-1, at which
time the controller outputs y=0 until the
control error is again bigger than 1.
The figure below shows the control error
con.feeBac.y
and the control signal
con.y
.
