Abstract

The objective of this project is to investigate the sensorless control methods for PM Synchronous machines. A sensor less method of high speed control is proposed based on the modulation of Space Vector Pulse Width Method. The conventional control scheme has some problems such as low efficiency, low switching frequency and switching losses. In order to avoid the above mentioned problems, VSI FED PMSM sensor less control is implemented. In addition SVPWM technique provides flexible control of output voltage and output frequency for Permanent Magnet Synchronous Machines. This Space Vector Modulation is implemented to prevent the distortion due to low switching frequency. A detailed study and analysis regarding the influence of low switching frequency, frequency loss and efficiency is carried out. It is found that, by using the proposed scheme and modulation scheme and by the proper control of VSI fed PMSM can be estimated for sensor less operations. Experimental results are provided to verify the proposed control method.
