Hi Peter,
theese aktuators are also sold with a build in potentiometer as position feedback. IMHO is this better than counting the pulses from the optical feedback. You have to count the pulses and have to know the moving direction of the actuator. With a potentiometer for each motor you just have to use two of the analog inputs of your microcontroller and then just compare them (the one from the main and the one from the aux. motor) and then generate a corresponding control signal.
You have to set a dead band and may be an easy filter for eliminating interferences.
Kind Regards
Andreas
