 PID
Controller
PID stands
for "Proportional/Integral/Differential". These
terms describe how the Component changes the value of its
output (an Analog or Quasi-Analog Component) and thereby brings
some object or device to a desired state. The PID allows you
to easily specify a setpoint value (the desired state) and
an Analog Component to monitor the object under control. This
is called a closed control-loop, and creating one with microCommander
is as easy as dragging and dropping a PID Controller Component.
For example:
You can use a PID Controller to heat a room a very specific
temperature. It will gradually adjust an output, such as power
to a baseboard heater, depending on the value of it's input,
a thermistor sensor, for instance. The PID will precisely
control the heater so that the room's temperature approaches
and converges upon a setpoint (i.e. the desired room temperature).
You can
easily calibrate or 'tune' your PID Component by setting Proportional,
Integral, and Differential constants to minimize overshoot
and oscillation about the setpoint. Change the speed at which
your PID reacts by setting an Integral Adjustment constant.
All of these can be set using a simple fill-in-the-blank form.
No programming. No debugging.

 On/Off
Controller
The On/Off
Controller Component is used to monitor an Analog Component
source to control a Digital Component output. A setpoint can
be specified such that when the analog source rises above
that setpoint, it toggles the output. When it falls below
the setpoint again, the output is returned to its original
state.
For example,
you could use an On/Off Controller to maintain the water level
in a tank. Attach the On/Off Controller to a the power switch
of a pump and specify the desired level of the water by adjusting
the setpoint. The On/Off Controller monitors an analog sensor
which reads the level of the tank. As the water level drops,
the On/Off Controller will activate a pump to bring the water
back to specified setpoint again.
A deadband
can also be specified around the setpoint to prevent rapid
toggling of the output.
