In the classical model predictive control strategy, parameter variation will affect the system performance. In this paper, an extended-state-observer-based model predictive power control (ESOB-MPPC) strategy for three-level neutral point clamped (NPC) rectifiers is presented. Firstly, the system model is designed by taking into consideration the system uncertainties and the external disturbance. Secondly, inductance is estimated by forgetting factor recursive least squares (FFRLS) algorithm for the enhanced parameter robustness. Simulation results verify that the proposed method has good dynamic performance and parameter robustness.
