| Sumario: | Asymmetrical dual three-phase permanent magnet synchronous machine (DTP-PMSM) drives have ttracted the attention of the scientific community and the industry for high-performance electromobility applications. Fault tolerant operation is a desirable feature to guarantee the continuous operation of such life-critical systems. Commonly, field oriented control (FOC) following the vector space decomposition (VSD) representation is used for current regulation purposes, incorporating proportional integral and resonant (PI-R) controllers in the harmonic frame xy to eliminate open-phase fault perturbations. As an alternative, a novel model predictive resonant controller (MPRC) is proposed in this work for fault tolerant operation. Multiple-Input Multiple-Output (MIMO) tools are used to tune the controller in the theoretical analysis, supported by the disk margin method. The aim of this work is to provide an MPC-based solution with the same functionalities as of the conventional PI-R based fault tolerant control method. It is demonstrated that, unlike conventional approaches, the MPRC can provide phase compensation intrinsically and, with a correct parameter tuning, it results in a satisfactory post-fault performance. Extensive simulations in a high-fidelity electric drive model are presented to compare the MPRC features ith respect to conventional controllers. Finally, experimental results are provided, demonstrating the correctness of the proposal. |
