This paper focusses on a novel discrete-time reduced order neural observer for nonlinear systems, which model is assumed to be unknown. This neural observer is robust in presence of external and internal uncertainties. The proposed scheme is based on a discrete-time recurrent high order neural network (RHONN) trained with an extended Kalman filter (EKF)-based algorithm, using a parallel configuration. This work includes the stability proof of the estimation error on the basis of the Lyapunov approach; to illustrate the applicability, simulation results for a nonlinear oscillator are included. © 2010 World Scientific Publishing Company.

This paper deals with a novel training algorithm for a neural network architecture applied to solar radiation time series prediction. The proposed training algorithm is based in a novel bio-inspired aging model-particle swarm optimization (BAM-PSO). The BAM-PSO based algorithm is employed to update the synaptic weights of the neural network. The size of the regression vector is determined by means of the Cao methodology. The proposed structure captures efficiently the complex nature of the solar radiation time series. The proposed model is trained and tested using real data values for solar radiation. © Springer International Publishing Switzerland 2014.

In general, heart medical diagnosis devices are reliable and efficient; however, they are only present in huge or modern hospitals. Heart murmurs are one of the typical heart problems. In this paper, we propose a radial wavelet neural network (RWNN) classifier for heart murmurs (pulmonary insufficiency and tricuspid insufficiency). The extended Kalman filter (EKF) is used as a learning algorithm for the RWNN. The network inputs are dimensional features, extracted from real cardiac cycles, and three classification outputs. Proposed model classification accuracy is compared with a multilayer perceptron trained with Levenberg-Marquardt training algorithm and with extreme learning machine one. The proposed model is trained and tested using real heart cycles in order to show the applicability of the proposed scheme. © 2015.

This paper discusses a novel training algorithm for a neural network architecture applied to time series prediction with smart grids applications. The proposed training algorithm is based on an extended Kalman filter (EKF) improved using particle swarm optimization (PSO) to compute the design parameters. The EKF-PSO-based algorithm is employed to update the synaptic weights of the neural network. The size of the regression vector is determined by means of the Cao methodology. The proposed structure captures more efficiently the complex nature of the wind speed, energy generation, and electrical load demand time series that are constantly monitorated in a smart grid benchmark. The proposed model is trained and tested using real data values in order to show the applicability of the proposed scheme. © 2013 Alma Y. Alanis et al.

In this paper, a Higher Order Wavelet Neural Network (HOWNN) trained with an Extended Kalman Filter (EKF) is implemented to solve the wind forecasting problem. The Neural Network based scheme is composed of high order terms in the input layer, two hidden layers, one incorporating radial wavelets as activation functions and the other using classical logistic sigmoid, and an output layer with a linear activation function. A Kalman filter based algorithm is employed to update the synaptic weights of the wavelet network. The size of the regression vector is determined by means of the Lipschitz quotients method. The proposed structure captures more efficiently the complex nature of the wind speed time series. The proposed model is trained and tested using real wind speed data values. © 2011 IEEE.

This paper proposes a hybrid smart grid integrating wind, photovoltaic and batteries into an AC bus. The wind speed and solar irradiance variables are characterized with experimental data from a meteorological station and the generators are sized according to the power demand of the Mechatronics building in the UADY Faculty of Engineering. A management system based on multiagents is designed in order to measure and control the loads inside the building. The knowledge base of the multi agent system is aided with contrains functions and power generation forecast using neural networks. © 2011 IEEE.
