I am looking to control the extension of a pneumatic cylinder to a
I was hoping to feed the position of the cylinder (through a sensor
such as a pot) back to a simple analog PID controller that would shut
a pneumatic valve on or off depending on where the cylinder is.
In my research I have come across expensive and complicated digital
PID controllers. I have been unable to find a simple analog pid
controller. I could model the system and build my own pid controller
with discrete op-amps and the such, but I need 8 of these controllers
and that approach becomes difficult when multiplied by 8.
Does anyone know if such a product exists, or am I completely off the
deep end with this approach?
