A new Elman neural network and its dynamic properties

Abstract

Elman neural network was one of the dynamic recurrent neural networks. In this paper, a new modified Elman network was proposed first. Then the dynamic characteristics of Elman series neural network are fully discussed. The theory study proved that the new Elman network inherently has proportional (P), integral (I), derivative (D) properties and traditional Elman networks only have PI or I characteristics. Simulation results based on ideal mathematical model show that the PID Elman network is prior to the modified Elman network in identifying nonlinear dynamic system.
