I am not sure that P is appropriate for a speed controller. The point is that P = 0 when the speed is correct. But you don't want 0 PID output when the speed is correct, or the speed will stop being correct. So, a speed loop might want to be mainly FF0 and I. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
