  1. Hello world, I have set AutoTune PID regulation of water level in my last Small Hydro Power Plant project. Most of the time the regulator works excellently but sometimes it starts to oscillate. The level in the river is rising and the power of the turbine is rising too. After some minutes the level starts to fall and the output power is falling also. The operator of the plant has to start new AutoTune cycle and everything is OK again for next months. My question is: Do you have some idea how to detect the situation when the regulation is oscillating (and eventually start AutoTune without operator intervence)? Thank you for any advices.
