These codes are really helpful gpsmikey thanks. I already found the article you've recommended me last time but didn't really understood them all. So I'll give this one again another try and see if th ...

Over time the sum should average to zero as positive and negative errors are added. In PID loops it is common to limit integrator "windup" for step changes in input by limiting the range of ...
