Parameter Sensitivity Analysis for 3-Φ Synchronous Reluctance Motor: A Critical Evaluation

In this paper, a modified three-phase synchronous reluctance motor model based on stator-fluxes and rotor-fluxes in synchronously rotating reference frame is presented. Being a nonlinear system, three-phase synchronous reluctance motor state estimation is carried out using extended Kalman filter. Additionally, parameter sensitivity analysis is performed to convey which parameter is critical in case of actual motor and model parameters mismatch. Extensive simulation studies are performed under different machine operating conditions and machine model uncertainties. The simulation studies are verified on a 5.5 kW synchronous reluctance motor using MATLAB software. The validity and effectiveness of the proposed model is verified by simulation results.
