AB The inherent fault-tolerant capability of multiphasemachines is highly appreciated, but it requires fault detection andlocalization together with a reconfiguration of the control scheme.When the multiphase machine is regulated using finite-control setmodel predictive control (MPC) strategies, the reconfigurationinvolves the use of different transformation matrices, cost functions,and current references for each of the multiple open-phasefault (OPF) scenarios. Aiming to simplify this procedure and addfurther robustness, this paper explores the possibility to achievea natural fault-tolerant capability by maintaining the prefaultcontrol strategy after the fault occurrence. For this purpose, thispaper first analyzes the two main reasons why MPC-regulatedmultiphase drives misbehave in the event of an OPF: the voltagevector shifting and the search for incompatible goals. In thenext step, a version of the MPC that includes virtual-voltagevectors (VVs) is tested for the first time in postfault situationand it is compared to conventional MPC technique. Extensiveexperimental results reveal that, while MPC misbehaves in theevent of an OPF, the VV-MPC provides a satisfactory ripple-freepostfault performance. This finding has two significant implicationsfor industrial applications: the postfault operation is highlysimplified and, at the same time, the fault-tolerant multiphasedrive becomes immune to fault detection errors and delays.
