Abstract

In this paper fuzzy logic and neural network methods were used to model simulated nonlinear steady-state data. Two different cases of training and checking data sets were generated: ideal data without noise and realistic data with added noise and other nonidealities. Both techniques were fitting the ideal case data almost perfectly. The fuzzy logic and neural network models were also able to roughly predict the realistic case data. 1. Introduction Both neural networks and fuzzy logic inference systems have been proved to have capabilities of universal approximators. Thus they can both be utilized in modeling of complicated nonlinear processes (Juditsky1, Wang2). Rotating disk filter is a complicated nonlinear process, w
