Se pretende ajustar automáticamente el punto de operación al que impone la demanda mediante el control combinado de carga y gasto.Se presentan resultados de simulación en ambiente Matlab  ® /Simulink con modelos obtenidos a través de vías analíticas y comprobados con técnicas de identificación experimental. Los resultados muestran que el ajuste único del punto de operación mediante la regulación por carga a pesar de tener mejores prestaciones que la regulación del gasto y ser la más empleada en las micro-turbinas hidráulicas, no aprovecha de forma óptima el portador energético. Por último, se presentan los resultados de simulación, algunas consideraciones sobre su desempeño, limitaciones y trabajos futuros.]]></p></abstract>
