Abstract

A new strategy is proposed to control interior permanent magnet generators in\ndc microgrids interfaced through an active rectifier. The controller design is\nbased on the decomposition of the system dynamics into slow and fast modes\nusing singular perturbation theory. An inner current controller is developed\nbased on output regulation techniques and an outer voltage controller is\nproposed using Nonlinear Model Predictive Control (NMPC). The NMPC regulates\nthe dc bus voltage and minimizes the ac side losses. Simulation results are\nthen presented based on realistic conditions for aircraft power systems.\n
