Approximation of non-autonomous dynamic systems by continuous time recurrent neural networks
C. Kambhampati, Freddy Garces, Kevin Warwick · 2000
This work provides a framework for the approximation of a dynamic system of the form x/spl dot/=f(x)+g(x)u by dynamic recurrent neural network. This extends previous work in which approximate realisation of autonomous dynamic systems was proven. Given certain conditions, the first p output neural units of a dynamic n-dimensional neural model approximate at a desired proximity a p-dimensional dynamic system with n>p. The neural architecture studied is then successfully implemented in a nonlinear multivariable system identification case study.
