I've never messed with PID's but I'm working on a project that I thought would be simple until someone told me that I needed to calibrate my system to another system using PID's.
So here goes with the question. I have a pedistal that moves in the up/down (elevation) and right/left (azimuth) positions. I am to track an object based on elevation and azimuth readings from another pedistal. So before I can track the object I need to sync, or calibrate, my tracking system to the other system. The way this is done is by pointing both systems to the same location (say the top of a mountain). If the master system reads 35 degrees azimuth and 88 degrees elevation and my system reads 34.02 degrees azimuth and 89.20 degrees elevation I need to fine tune my system. I can do this by using 2 slider bars that control the up/down and left/right movement of my system so that I can manually move my system to the correct location. Once my system is pointing in the right location, I'm guessing I store some value. Once the system is calibrated, I should be able to track pretty close to where the master system is telling to be. So thats pretty much all I know I should do. But I don't know how to develop this with PID's. Does anyone have any suggestions, example, etc? Thanks. --cjm
