Maximum Torque per Ampere Sensorless Speed Control of SynchronousReluctance Motors

Nowadays, Synchronous Reluctance motors (SynRM) have received much attention for manyapplications such as tractions applications and become more potentially important in theapplication of AC motor drives. Since modern speed control methods are based on theelimination of the number of sensors in industrial applications and also to reduce the cost andimprove reliability, sensorless speed control methods have been proposed for SynRM drives.This paper presents a robust and high-performance sensorless control scheme for SynRM.Also, the maximum torque per ampere (MTPA) control strategy is used to reduce the rotorchopper losses and increase the whole drive system efficiency. The performance of theproposed method has been investigated and finally, simulation results are taken fromMATLAB/SIMULINK to confirm the effectiveness of the proposed sensorless speed controlsystem for the SynRM
