In this study, adaptive neuro-fuzzy inference system (ANFIS) was applied to estimate the parameters of a coagulation chemical dosing unit for water treatment plants. The dosing unit has three input variables (sudfloc 3835, ferric chloride and hydrated lime flow rates) and two output variables (surface charge and pH values). The ANFIS model is compared with(More)
Fuzzy dynamic modelling and predictive control of a coagulation chemical dosing unit for water treatment plants. Abstract In this paper, a fuzzy model predictive control (FMPC) strategy is proposed to regulate the output variables of a coagulation chemical dosing unit. A multiple-input, multiple-output (MIMO) process model in form of a linearised(More)
The need for processes to be operated under tighter performance specifications and satisfy constraints have motivated the increasing applications of nonlinear model predictive control (MPC) by the process industry. Nonlinear MPC conveniently meets the higher product quality, productivity and safety demands of complex processes by taking into account the(More)
In this study, a mechanistic model of a chemical dosing unit is proposed to facilitate the applications of advanced control strategy for coagulation process in water treatment plants. The procedures adopted in this study may be extended successfully to other coagulant dosage systems using different types of coagulants and pH adjustment chemicals. The(More)
