That looks pretty nifty. Looking at the code, it exposes metrics
through sysctl. Be sure to give
Hi,
I'm curious, it looks like Kd is quite significant by default, I assume
to limit the slew rate of the output.
Given that the error is an integer, and pidctrl_daemon() is called at
irregular intervals, it seems to me that the derivative will be very noisy.
In my experience with PID

Log:
Add a generic Proportional Integral Derivative (PID) controller algorithm and
use it to regulate page daemon output.
This provides much smoother and more responsive
