bldc motor control

i am using arduino uno with matlab to control the BLDC motor in open and closed loop control but it does not read the analog reference signal what is the problem?

No idea.

Maybe you can tell me what is wrong with my car. It's a white one.

Code please? What analog reference? What doesn't read the analog reference. How are you getting feedback inclosed loop. What model Arduino? Why are you using Matlab? How are you driving the BLDC motor? Tom... :)

The analog reference is an input pin to the Arduino used to set the full scale point for analogRead.
