Abstract

A neural network controller which is used for controlling unknown discrete-time DARMA systems is described. In a first stage, a two-layered neural network is used to estimate the unknown plant dynamics. The Widrow-Hoff delta rule is used as the learning algorithm for this network so as to minimize the difference between the plant actual response and that predicted by the neural network. In a second stage, the control law is generated online using a second two-layered neural network so that the plant output is brought to a desired reference signal. Simulation examples are presented to evaluate the design
