摘要
This paper deals with a control strategy for marine current energy conversion systems based on 5-phase permanent magnet synchronous generator (PMSG) in both normal and faulty operation modes. The PMSG currents are controlled by the finite control set model predictive control method. Based on future behaviors of the system, which are predicted from a finite set of possible switching states of a 3-level 5-phase inverter, the optimal voltage vector, which minimizes the cost-function, is selected. When an open-circuit fault occurs, the reference currents are reconfigured to ensure continuous and safe operation of the system and to avoid high torque ripple. Several simulations are carried-out for validation purposes of the proposed fault tolerant control strategy.
