Hi Guys,
I am new here but definitely excited to get started on my first project!
I am working with some colleagues to develop an open-source ventilator solution. One piece of the puzzle we are working on is creating a closed-loop pressure control regulator. The current design configuration uses a Voice Coil Actuator (effectively a DC motor), with positive current turning a pneumatic servo-valve "ON" and negative current exhausting the gas to the atmosphere. Zero current is an idle position.
I think we want to use a Teensy 4.0 combined with an H-bridge to perform closed-loop pressure control on the pressure circuit. We want to use a PID control strategy to ultimately control the final pressure output. The feedback signal will be a pressure sensor output stage. Finally we want the tunable variables to be stored in flash memory on the Teensy 4.0.
With that said, I am a bit stuck on the code side of things. I am very new to the Arduino family and I am curious as to where to start.
Thanks
Dan
