Re: Speed Controller Design

Jesse,
There are pros and cons for both types. In the application you describe, I believe either type will work, but the PID variables will be vastly different between the two types. Whatever non-linearity might be present is capable of being corrected in software. Please be advised that many people have reported that window motors don't play well with Jaguars. I have nothing more at this point in the discussion than that there appears to be a interaction with both the locking pawls internal to the window motors and some interaction with the armature/worm gear interface when using the Jaguars. Some teams reported no problems with this combination. I am still looking for input from teams who have been doing off season testing.
