Vector Control of Permanent Magnet Synchronous Motors Using Embedded Coder & Sensorless Control Simulation Using Sliding Mode Observer

Abstract

Availability of cheap and better performing floating point digital signal processors has given a boost for the digital control market in the field of power and motor control.In addition to that availability of graphical programming tools for micro-controllers has driven research into the ease of use and effectiveness of DSP micro-controllers for power and motion control in the academic field as well as in the industry. In that direction a floating point DSP micro-controller was used to perform vector control of permanent magnet synchronous motor. Matlab Simulink Toolbox:Embedded Coder, an optimized code generation toolbox for embedded systems was used to develop the required code. Also, a study of space vector pulse width modulation techniques was carried out to operate AC machines at reduced harmonic distortion. The effectiveness and ease of programming of floating point DSP micro-controllers was shown. It is recommended to be used in academic and research centers for the ease of development, effective performance and reduction in time to market. Along with this a simulation model for sensorless control of permanent magnet synchronous motor is provided.
