I am building a fly-by-wire throttle system and need to control a servo on a throttle body. I have a throttle body with what i assumed was a servo attached, but i discovered it was only a DC motor. There are two potentiometers on the output shaft, and they feed back to the ECU, which I unfortunately don’t have. I assume the ECU then provides a closed loop feedback to the motor to essentially turn it into a servo. While i’m sure i could do this with the Arduino i’m using, I am worried about the settling time and efficiency of my control system. Since this is going to be controlling the fuel going into an engine, I would like something a little more professional. I would like to avoid mounting a servo to the system, right now the DC motor is packaged really well and it would be a pain to mount a servo.
Would the JRK 21v3 work for this? It says it can provide closed loop feedback for position control, so it sounds like it to me. Does anyone have any recommendations?
