Abstract— This paper proposes to describe Field oriented control (FOC) of Permanent Magnet Synchronous motor (PMSM) using MRAS speed observer for sensorless control of drive. The aim of the proposed sensorless control is to improve performance and robustness of PMSM drive under load variations is presented in this work. Also in this the conventionally used PI controller in adaption mechanism of the MRAS observer is replaced by a FLC. The improvement in speed response during load variations is shown by comparative study between conventional PI and fuzzy PI. The effectiveness and validity of the proposed control approach is verified by simulation results.
Keywords- permanent magnet synchronous motor; speed control; Field oriented control; model reference adaptive system.
I. INTRODUCTION Nowadays, permanent magnet synchronous motor(PMSM), has been widely used in high performance variable speed in many industrial applications, due to its high efficiency, high ratio of torque-to-inertia ratio, high power factor, fast response and rugged construction .The PMSM has increasingly used in electrical vehicles , aircraft, nuclear power station ship engines, robotic automation, escalators and industrial servo drives [5]. The control methods used for the permanent magnet synchronous motors are: V/f control, field oriented control and direct torque control [4]. Field oriented control was introduced to control method of the PMSM, which achieve fast dynamic response and the flexibility normally obtained in control of separately excited dc motor. Position sensor with higher quality is a necessary component part of the drive system employed in industrial and automotive
