Abstract : Due to severe mathematical modeling and calibration difficulties open-loop feedforward control is mainly employed today for wastewater denitrification, which is a key ecological issue. In order to improve the resulting poor performances a new model-free control setting and its corresponding "intelligent" controller are introduced. The pitfall of regulating two output variables via a single input variable is overcome by introducing also an open-loop knowledge-based control deduced from the plant behavior. Several convincing computer simulations are presented and discussed.
Keywords : model-free control intelligent P controllers robustness performance feedback control design denitrification biofiltration artificial intelligence knowledge-based control wastewater - treatment - treatment biological algebraic estimation techniques
