“…In addition, since the motor current is not directly controlled to achieve maximum torque per ampere (MTPA), the efficiency is not guaranteed to be optimum. A substantial amount of research work has been carried out the efficiency and stability of PMSM drives using V/f control [13,14,[16][17][18][19].…”

Permanent Magnet Synchronous Motors (PMSM) have been gaining ever-increasing popularity in many applications thanks to their advantages such as long life, high torque and power density, excellent efficiency, etc. The applications of PMSM could be found in almost every industry such as home appliances, robotics, flywheels, industrial automation, electric vehicles, so on and so forth. Various control methods have been proposed for PMSM to attain satisfying performance with different application needs. For example, V/f control with stabilization loops could be used to control fan-type applications where dynamic response is not a must but efficiency and quietness matter. Field Oriented Control (FOC) is the dominant PMSM control method that achieve good dynamic response, smoothness and energy efficiency.Direct Torque Control (DTC) excels FOC in simpler control structure and supreme dynamic response but suffers from variable switching frequency and severe torque ripples. These defects generally lead to poor torque and flux regulation, high current harmonics and acoustic noise.
