maximum torque per ampere sensorless speed control of synchronous reluctance motors

Nowadays, synchronous reluctance motor (synrm) has received much attention for many applications and becomes more potentially important in the application of ac motor drives. since modern speed control methods are based on the elimination of the number of sensors in industrial applications and also to reduce the cost and improve 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 rotor chopper losses and increase the whole drive system efficiency. the performance of the proposed method has been investigated under different conditions and finally, simulation results are taken from matlab/simulink to confirm the effectiveness of the proposed sensorless speed control system for synrm
