Current-sensors fault tolerant control system for electric drives: experimental validation

Abstract

This work presents the experimental validation of a current sensors fault tolerant control system (FTCS) for induction motor drives. This FTCS has the ability to diagnose single and multiple current sensor faults and to perform a control loop reconfiguration in order to keep the drive running in the event of faults. Operation is verified using a variable speed drive with a 0.75 kW squirrel cage induction motor controlled by a field oriented vectorial strategy implemented in a Texas Instruments DSP TMS320F28335.
