Abstract
In this study, single-phase current sensor Fault-Tolerant Control (FTC) for Three-Phase Induction Motor (TPIM) drives using a flux observer is proposed. In the proposed FTC scheme, a 3rd difference operator executes the Fault Detection (FD) task and the reconstruction of the faulted current is achieved through a flux observer. The presented FTC system is able to switch TPIM drive systems from normal mode to the faulty mode suitably. The proposed method in this study can be utilized in many industries particularly in electric vehicles, medical devices, and aerospace where TPIM drive systems are needed to continue the desired operation even during fault situations. The effectiveness of the proposed FTC system is confirmed by experiments on a 0.75kW TPIM drive platform.
