One-Step Weights Updating Back-Propagation Neural Network for Nonlinear System Identification

Article Preview

Abstract:

Given that many filters such as least mean squares and recursive least squares which are not able to deal with nonlinear system. In this paper, a nonlinear system identification technique using a specially designed neural network is investigated. Precisely, a power-activated back-propagation neural network is first constructed. Then, a high efficient weights updating method which only requires one-step iteration in its training session is presented. The system identification performance is evaluated through MATLAB simulations. The simulation results validate the one-step weights updating method and show satisfactory nonlinear system identification performance.
