Resumen:

This paper presents the simultaneous coordination for back to back control scheme using a B-spline artificial neural network. The main task is that the power converters operation adapt by itself during the grid changes. The basic problem consists of tuning the PI controllers simultaneously when the system and load are subjected to disturbances. The B-spline neural network is an efficient tool to implement the adaptive tuning controllers, with the possibility of carrying out this task on-line taking into account the systems' non-linearities and uncertain situations. The applicability of the proposal is demonstrated by simulation in a back to back configuration connected to a single load. Results show that the proposed controllers' tuning is comparable to that obtained by a conventional design, without requiring a detailed model analysis. The results are analyzed in detail and some important conclusions are drawn. © 2012 IEEE.
