Permanent Magnet Assisted Synchronous Reluctance Motor is one of the new motors introduced in transportation industry, which have been introduced as a possible tractions motors in hybrid electric vehicle applications. Achieve maximum torque per ampere (MTPA), knowledge of the motor parameters is necessary. Due to the high ambient temperature inside the engine cavity and also saturation effect, variation of the motor parameters such as inductances and permanent magnets flux density is not avoidable. In this paper, motor equations in biaxial system are described, then a method is presented for vector control considering maximum torque per Ampere. Then, this method is implemented on a Reluctance Synchronous Motor Reinforced with Magnet using Simulink. Simulation results show well performance of the designed control system in a wide range of speed.
