Abstract
This paper presents an adaptive two-configuration predictive control for the combustion process coupled application of an inverter-fed thermo-hydraulic linear permanent magnet synchronous generator (LPMSG). The therefor required rectangular current trajectories and desired high efficiency are achieved by combining loss minimizing switching sequences and force ripple reducing duty cycles. Since previous two-configuration predictive controls use carrier modulation and minimize the total current deviation, the proposed scheme is inherently better suited for this application. Compared to a conventional field oriented control, the simulation results reveal a superior rise time shortened by 49% and a reduction of the total inverter losses up to 36 %.
