Abstract

This paper mainly focuses on studying the torque control with maximum torque per ampere (MTPA) technique based on fuzzy theory and without dealing with complex computation of torque control optimization for the interior permanent magnet synchronous motor (IPMSM). The IPMSM control system generally includes position, velocity and current loops. The speed command will compare with the actual speed sensed from an encoder to generate the inner-loop current command. Analog-to-digital converters (ADCs) receive the phase current data from current transducers so that the difference between the current commands and the sensed data will be processed to be the motor drive signals. In addition, the space vector pulse-width modulation (SVPWM) is employed in the firmware architecture of microcontroller unit (MCU). Generally, the MTPA spends considerable computation such that a high level chip is indispensable. This paper proposes fuzzy MTPA control to improve it. Finally, dsPIC30F4011 from Microchip based IPMSM drive system verifies the proposed method.
