Abstract

This paper presents a prototype hardware implementation of a continually online trained artificial neural network to adaptively identify the electrical dynamics of an induction machine and control its stator currents from a pulse width modulated voltage source inverter. A single transputer based hardware platform is described and the effects of computational speed limitations on the controller bandwidth are discussed. Captured results are compared with simulation results to practically verify the success of the adaptive neural network identification and control scheme
