El control de máquinas de inducción multifásicas avanza con la incorporación de controladores predictivos que actúan directamente sobre el inversor sin mediar moduladores. Se lleva a cabo en tiempo discreto, mediante una optimización exhaustiva de los estados posibles del inversor. La optimización utiliza una función de coste que penaliza desviaciones de la referencia y otros efectos indeseados, por lo que su diseño tiene gran importancia en el comportamiento en bucle cerrado. En este artículo se presenta una nueva estrategia para el diseño de funciones de coste y su optimización. Se presentan resultados de simulación correspondientes a una máquina de cinco fases y se compara con el método tradicional, todo ello en el contexto de control predictivo de corrientes de estátor.Descargas
