N2 - This letter proposes a new modified model predictive control (MPC) to compensate for voltage and frequency deviations with higher bandwidth for an ac shipboard microgrid (MG). The shipboard power system (SPS) and islanded MGs have a reasonable analogy regarding supplying loads with local generations. However, a great number of vital imposing pulse loads and highly dynamic large propulsion loads in the SPS make the frequency and voltage regulation a complicated issue. Conventional linear control methods suffer from high sensitivity to parameter variations and slow transient response, which make big oscillations in the frequency and voltage of the SPS. This letter addresses the problem by proposing a novel finite control set MPC to compensate for primary frequency and voltage deviations with higher bandwidth and order of magnitude faster than the state of the art. Furthermore, a single input interval type-2 fuzzy logic controller is applied in secondary level to damp the steady-state deviations with higher bandwidth. Finally, hardware-in-the-loop experimental results prove the applicability of the proposed control structure.
