• This paper presents an improved current sensor fault-tolerant control for vector control of induction motors. This work aims to reconstruct the three current phases even under the failure of two or three current sensors and make the vector control in service under this situation. Therefore, the proposed scheme is made up of three blocks, vector control, sliding mode observers for the diagnosis process, and the reconfiguration algorithm. In the case of the failure of two or three current sensors, we will use the DC-link current sensor of the inverter to reconstruct the three phases currents. In addition, a synchronization technique named as PFCE (Positive Fundamental Component Estimator) is used to obtain results similar to real currents. Simulation results are presented discussing the studied approach.
