Abstract
(EN)
The invention describes a predictive control method for rectifiers/inverters, which defines mathematical models that represent a load/network and a converter/inverter, to then define control objectives for the load/network and the converter/inverter. For both cases, single or multiple cost functions are defined, depending on the nature of the control objectives. If the control objectives are the same, a single, variable cost function is used; if not, there are as many cost functions as control objectives. Subsequently, the possible states that minimise the cost function associated with the load/network model are evaluated and determined, and said states are used to minimse the cost function associated with the converter/inverter model. The process of evaluating objective functions is repeated with redundancies.

Se describe un método de control predictivo para rectificadores/inversores, el cual define los modelos matemáticos que representan la carga/red y convertidor/inversor, para luego definir los objetivos de control para la carga/red y el convertidor/inversor. Para ambos casos, se definirán funciones de costo únicas o múltiples dependiendo de la naturaleza de los objetivos de control. Si son los mismos objetivos de control, se usará una única función de costo variables, caso contrario, se tendrá tantas funciones de costos como objetivos de control. Posteriormente se evaluarán y determinarán los estados posibles que minimicen la función de costo asociada al modelo de carga/red y se utilizarán dichos estados para minimizar la función de costo asociada al modelo del convertidor/inversor. Luego se repetirá el proceso de evaluación entre funciones objetivos con las redundancias.

L'invention concerne un procédé de commande prédictive pour redresseurs/onduleurs, lequel définit les modèles mathématiques qui représentent la charge/le réseau et un convertisseur/onduleur, pour ensuite définir les objectifs de commande pour la charge/le réseau et le convertisseur/onduleur. Dans les deux cas, des fonctions de coût uniques ou multiples sont définies en fonction de la nature des objectifs de commande. Si les objectifs de commande sont identiques, on utilise une unique fonction de coût variable, dans le cas contraire, on utilise autant de fonctions de coûts que d'objectifs de commande. Ultérieurement, les état possibles qui minimisent la fonction de coût associée au modèle de charge/réseau sont évalués et déterminés et ces états sont utilisés pour minimiser la fonction de coût associée au modèle du convertisseur/onduleur. Ensuite, le processus d'évaluation est répété entre fonctions objectifs avec les redondances.
