This paper presents a vector-controlled implementation strategy that can be realized in the absence of voltage and current sensors. It is proposed that, in order to decouple the torque and flux in the determination of the three-phase voltage reference commands, both stator and rotor currents in the stationary and rotating frames can be derived from the corresponding rotor flux-oriented vector control requirements and motor dynamic equations. A sensitivity analysis to study the effect of parameter deviation or mismatch is also investigated. Simulation results are presented to demonstrate the feasibility and performance of the proposed methodology.
