چکیده

This study addresses the proposition of neural network (NN) adaptive control for a class of nonlinear systems using fuzzy reasoning. In first step, an ideal control law is established based on feedback linearization technique and certainty equivalence. Then the NN system is introduced on line to approximate this ideal control law. The parameters of the NN system are on-line adapted and changed according to the gradient descent law, which will be approximated in part by a fuzzy inference system. In other words, instead of using the popular back propagation technique. we use an on-line simple fuzzy inference system to approximate part of the gradient descent resulting adaptation law.

The use of wavelet - artificial neural network and adaptive neuro fuzzy inference system models to predict monthly precipitation

Precipitation forecasting due to its random nature in space and time always faced with many problems and this uncertainty reduces the validity of the forecasting model. Nowadays nonlinear networks as intelligent systems to predict such complex phenomena are widely used. One of the methods that have been considered in recent years in the fields of hydrology is use of wavelet transform as a moder...

Adaptive Leader-Following and Leaderless Consensus of a Class of Nonlinear Systems Using Neural Networks

This paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (MIMO) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. The agents may have different dynamics and communicate together under a directed graph. A distributed adaptive method is designed for both cases. The structures of the contro...

Controlling structures by inverse adaptive neuro fuzzy inference system and MR dampers

To control structures against wind and earthquake excitations, Adaptive Neuro Fuzzy Inference Systems and Neural Networks are combined in this study. The control scheme consists of an ANFIS inverse model of the structure to assess the control force. Considering existing ANFIS controllers, which require a second controller to generate training data, the authors’ approach does not need anot...
