Control a Linear actuator (LD20 with pot) with PI controller

[pxd853]

Hi,

So I have this linear actuator ( attached file) that I want to control with a myRIO-1900 board. Basically, this is what I want to do: I want to move a load to a desired position and hold it there. 

I've been able to change the direction and the actuator runs until it reaches the end of stroke in either direction. I've also set a duty cycle manually to control the speed of the motor.

What would be the best course of action to control move the load to a desired position?

kind regards,

Patricia

Hi Patricia,

What would be the best course of action to control move the load to a desired position?

Convert "position" to "pot resistance value". Then move the actuator until you reach the desired resistance value(s)…

with PI controller

I guess there is a manual for your "controller" so read it to find specific information on your problem…
