I was wondering if there was anyone out there that had an implementation of a PID control loop in Verilog or VHDL. I am interested in it for a small motion control project of mine (personal not work or school). I would like to see Open Cores gain a PID controller and eventually give it a proper Wishbone interface. If you don't know what PID is take a look at http://www.motionvillage.com/training/handbook/resources/2000_08_pid_pos_loops.pdf for a brief introduction and block diagram. Thanks in advance. Adam

I have a PID implementation but not in VHDL. It is in PIC assembly. PID is not that difficult though to implement. I would even be interested in working with the PID VHDL. Take a look at http://www.colinmackenzie.net, my digital servo controllers with PID control are shown there on the first page. If you want to see the PID code drop me an email (personally, not on oc) and I will forward my code to you.
