RobustFuzzyPIDControl forASPWastewater Treatment System

Thispaper presents asimple design strategy of robust fuzzy PIDcontrol system fortheregulation ofa small activated sludge process (ASP)wastewater treatment plant, especially. Atfirst, fuzzy PIDcontroller isdescribed. Then, anovel control strategy ispresented considering the different operating modesandconditions. Finally, thefuzzy PIDcontroller anditsapplication toanactivated sludge wastewater treatment plant issimulated anddiscussed. Whichdemonstrates averyrobust nature.
