Resumen:
This paper presents the experimental validation of a control reconfiguration method based on virtual sensors in order to implement a single and multiple current sensor fault-tolerant electric drive. The virtual sensors are generated from a bank of state observers based on the induction motor model in real time. These virtual sensors allow the use of a field-oriented control strategy even when one of the current sensors is under fault. In case of multiple current sensor faults, a closed-loop scalar control strategy is used. Experimental results are presented for different operating conditions, demonstrating the operation and feasibility of the proposed reconfiguration method.
