Fuzzy neural network control of uncertain parameters system

According to the practical situation of wastewater treatment process, nonlinear model of activated sludge wastewater system is turned into uncertain parameters model. To this model, controllability and stability analysis are given and a state feedback to improve its stability is designed. A fuzzy neural network controller is proposed for this model, and by means of simulation the result shows that such application is feasible. When compared with traditional fuzzy control, this fuzzy neural network control strategy shows excellent robust and good dynamic characteristics to control the above uncertain parameters system.
