Hi Alan, thank you for your patch. I have a few, probably dumb questions: * Isn't the your new integrator filter the same as a pi-simple-controller with Kp=1 and no min/max clamping? * What would you think about extending the exponential filter to make it behave like a high-pass or low-pass

Torsten Thanks for looking at my code. Yes – there is already an integrator in the PI and PID filters. But the same can be said for derivative and gain. Min/max clamping via u-max and u-min appears to be working correctly in my integrator. Having a specific integrator filter makes the
