Sensitivity of the currents input-output decoupling vector control of the DFIM versus current sensors fault

The goal of this paper is a Doubly Fed Induction Machine (DFIM) working in motor mode and supplied by two voltages PWM inverters, in stator and rotor sides. Effects of current sensors faults on the currents input-output decoupling in the Stator Flux Oriented Vector Control (SFOVC) are analyzed. A sensitivity study is carried out considering both stator and rotor current sensors failure, under different working conditions and a large speed range. Stator flux coefficient sensitivities emphasize the required accuracy of the currents sensors to guaranty the correct angle orientation and the required level of control performances. Matlab-Simulink simulation results are given and illustrate this sensitivity analysis.
