Abstract


A nonlinear model for Practical study of fluid system that includes Benfield Solution (B.S.) in urea plant system is presented .The present work measures the practical values of the quantity and level of B.S. inside different containers of the process and study the dynamic behavior of that process by constructing a deterministic, lumped, parametric, continuous time model using transfer function and state space. This model is used to design a suitable control system. The experimental studies beside the theoretical analysis are carried with proper results. Adaptive neural network based fuzzy inference system (ANFIS) as an intelligent neuro -fuzzy technique used for modeling system and a given practical training data set is partitioned into a set of clusters based on subtractive clustering method
