  • Abstract:
  • This study proposes a new speed estimation method based on the Model Reference Adaptive System (MRAS) that calculates the rotor speed and position in a vector controlled Synchronous Reluctance Motor (SynRM) drive. This allows the drive to successfully operate without a speed sensor. In the rotor reference frame (dq-axes), the reactive power 'X' defined in terms of voltages and currents is the functional candidate selected to construct the MRAS system. Reactive power is a good functional choice because it removes the need for stator resistance in the adjustable model, which makes the speed estimator independent of changes in stator resistance. Other than that, the customizable model's speed estimator is devoid of integrator and derivative terms. Furthermore, unlike injection-based speed estimators that are documented in the literature, the speed estimator is hardware-independent and only requires basic processing. Finally, thorough simulations performed using the MATLAB/SIMULINK platform are used to confirm the efficacy of the suggested speed estimator. Simulation results have been verified through HIL 402 real-time simulator.
