Linear Actuator Control with Setpoint and Feedback "Generic Actuator"

[nhargrove]

I am trying to control the positon of the actuator using a setpoint and the feedback from the actuator itself.  I am currently changing the direction by reversing the polarity of the wires going to the actuator, controlled by relays that are assigned to a relay fieldpoint module.  I have feedback off a potentiometer located on the actuator and reading that with an AI Fieldpoint module.  The object is for me to be able to input a setpoint and control the position of the actuator based off the feedback,"setpoint too high, actuator has to extend and if the setpoint is to low, the actuator has to rectract.  The problem i am having is holding the position and not over shooting it.  Is there any created examples that can help me with this.  I would really appreciate any help

nhargrove, 

As far as examples go, you can search our NI Example Finder by going to LabVIEW>>Help>>Find Examples and searching 'actuator' or other terms you think might be helpful. Currently I see one example that has to do with an actuator. 
A second method that may be helpful is to visit www.ni.com and search for actuator and then filter by examples. This will list all of the community example code including actuator information. You might also try different search terms to help find examples. 

If that doesn't help, you might consider posting this in our FieldPoint Family forums to get a more interactive community response.
