Implementation of Improved Sliding Mode Observer and Fault Tolerant Control for a PMSM Drive

Abstract : This paper presents the development and experimentation of Fault-Tolerant Control (FTC) for sensorless Permanent Magnet Synchronous Motor (PMSM) drive with stator resistance tuning. In the fault-tolerant inverter, a redundant leg is added to replace the faulted leg. Consequently, the proposed inverter is a modified topology inverter with fault-tolerant capability, which can be configured as 3-phase 8-switch inverter. The detection of the faulty leg is based only on the output inverter currents measurement. To make toggle to a redundant leg in case of fault occurrence, a Fault Detection and Isolation (FDI) algorithm is proposed in this paper. Experimental results are presented using a 1.4kW, three poles three-phases PMSM. These results show that the proposed FDI algorithm is able to detect and to isolate the open-phase fault in PMSM drive.
