Permanent magnet synchronous machines (PMSM) are very popular in many industrial applicationssuchasinmechatronics, automotive, energy storage flywheels, centrifugal compressors, vacuum pumps, and robotics. This paper proposes Sensorless control for a PMSM speed drive which is based on aclosedloopcontrol system using a proportional and integral (PI) controller that is designed to operate in flux weakening regions under a constant torque angle.This Sensorless elementwasadopted for best estimating the PMSM rotor position based on its performance characteristicseliminatingthe need for speed sensorswhich are usually required insuchcontrol applications. To achieve this goal, apulse width modulation (PWM) control scheme was developed to work in conjuction with a field oriented motor controldriveusingSimulink.Thisinnovative control system was simulated assuming realistic circuit components to maximize the accuracy of the proposed model.Finally, simulation results obtained under different operation conditions at below and above the rated speed of the motorwere presented and discussed in this paper.
