APPLICATIONS OF NEURAL NETWORKS IN LEARNING OF DYNAMIC-SYSTEMS

One of the immediate applications of neural networks in the engineering field is pattern recognition and its extension to system identification. Three unique features of neural networks, namely, learning, high speed processing of massive data, and the ability to handle signals with degrees of uncertainty make such networks attractive to dynamical systems. The first step in analyzing such systems is to learn the dynamics of the system, i.e., system identification. A time-domain approach, using Hopfield network, and a frequency domain approach using spectral decomposition for identification of dynamical systems are presented. Simulation results are discussed.
