LabVIEW
DC MOTOR
What data do you need to acquire? The neural network aspect is probably not too relevant at this point, it is just the "box" that sits between the motor and the hardware to control it. So neural network, PID controller, whatever you will need an input to tell your "model" what the current parameter value is, then it will determine what output to the motor controller is needed to make that parameter meet some value criteria. A DC motor's supplied voltage, and the resulting current draw can be fairly easily measured, but don't necessarily tell you all that you need to know. To determine rotational speed will usually require an additional transducer, which can be as "simple" as a magnet on the motor's shaft hall-effect sensor detecting each time the magnet passes, or more complex like an optical encoder, which can give you the rotational direction as well as speed. Tell us what data you will need for this project and we can better help you determine how to get it.
