Sensorless Permanent Magnet Synchronous Motor Using Field Oriented Control or Vector Control Method based on Solar Power System

Abstract

Permanent magnet synchronous motor (PMSM) is an AC synchronous motor whose field excitation is provided by permanent magnet and has Sinusoidal back EMF waveform. In the Sensorless PMSM, rotor is the important part of this drive. Accurate rotor position information is important for a sensor less PMSM drive. In any kind of machine or drive is desirable to use a methodology which is very less depend on sensor and complicated circuits So in this article be used a mathematically field-oriented control (FOC) method. In this article, main object is control the variable speed and improve the efficiency of the PMSM motor. So PMSM control is control variable torque and axial flux to used vector control method. The main parameter of the PMSM drive is control the stator current and also find the rotor current (which does not measure directly) be apply for measurement is coordinate reference transformation. Used the basic concept of FOC model in this model concept is total current which take machine is inject on quadrature axis minimum current apply on direct axis. Current inject position is totally applied on quadrature align because direct align current is wastage so FOC technique desire give maximum power of the PMSM drive maintain its speed and efficiency. Also information of the rotor angle is very important give the correct information so be connected a feedback of the output of the parks transformation. All work is based on coordinate transformation like Clark transform and Park transform also its invers is applied in the article. Total work is represented computer MAT LAB Simulation and Experimental output is represented. PMSM application is used with increasing popularity of electrical vehicles, Power train is used the Electrical Vehicles and Industrial applications. Our work is designates the control system of the axial flux of the Permanent Synchronous Motor. For various applications is also operate on Renewable energy for powering PMSM motor with FOC model.
