Abstract

Permanent Magnet Synchronous Motor is versatile motor that have many advantages and it’s generally used in many industrial applications for high performance as variable speed drives. Permanent Magnet Synchronous Motor typically used in variety of industrial application in order to replacing classic DC motor and induction motor. Plus, this motor brings a huge advantage such as high efficiency, high power density, lower field copper loss and more sturdy construction because of the DC field winding of rotor is swapped by permanent magnet. Mostly, PMSM comes with a mechanical sensor such as encoder, observer or Hall effect sensor that reduced its reliability, additional cost, increased complexity and weight of the drive system. This report proposed the development and model a sensorless control of PMSM drives using Matlab/Simulink. The modelling of sensorless control of PMSM drives using voltage model based on Model Reference Adaptive Control (MRAC) based on Power Reactive Equation in order to estimate the rotor position. The performance of this sensorless control will be analyzed and compared to standard PMSM Drives in term of speed behavior and load disturbance. The results show that the MRAC based on Power Reactive Equation have lack in satisfies the speed estimation and load disturbance compared to standard PMSM using sensor. However, this project has successfully created a sensorless control of PMSM that suitable for middle speed range.
