Nonlinear PI Control With Adaptive Interaction Algorithm For Multivariable Wastewater Treatment Process

The wastewater treatment plant (WWTP) is highly known with the nonlinearity of the control parameters,thus it is difficult to be controlled.In this paper,the enhancement of nonlinear PI controller (ENon-PI) to compensate the nonlinearity of the activated sludge WWTP is proposed.The ENon-PI controlle...
