A neural network based feedback linearising controller for HVDC links

Abstract

Feedback linearization has been used successfully to address some of the practical control problems. This paper introduces a practical control philosophy for a point to point HVDC link, based on the above principle. The basic DC link equation has been used to evaluate the firing angle for the rectifier. An Adaline has been trained to identify the parameters of the simplified system model prior to the application of this control. The simulation results presented in this paper prove the advantage of the proposed control scheme.
