MW-rated Induction Motor Control equipped with Fault-Ride-Through Capability for an Electric Propulsion Ship using Model Predictive Control

This paper presents a novel speed control method equipped with fault-ride-through capability for a megawatt-rated electric propulsion ship based on model predictive control (MPC). The single MPC problem is formulated to minimize speed tracking error while satisfying the three major constraints: maximum current, torque gradient, and DC link voltage. This approach simplifies and clarifies the controller design process. The proposed MPC-based method demonstrates short settling time, no overshoot, optimized power usage while meeting all constraints. The effectiveness of the proposed MPC-based method is validated through simulation results.
