Design and Simulation Vector Control of Permanent Magnet Synchronous Motor

Motor drives are essential in many industrial applications such automotive, robotics, power and energy industry. The motor drives need the information of rotor speed to achieve speed control. Rotor speed can be measured by sensors attached to rotor shaft which sends the motor speed to the motor drive. However, using sensors in the rotating shaft is not always practical.. The entire PMSM control system is divided into several independent functional modules such as PMSM body module, inverter module and coordinate transformation module and Sinusoidal pulse width modulation (SPWM) production module and so on. we can analyzed a variety of simulation waveforms and it provide an effective means for the analysis and design of the PMSM control system PMSM (Permanent Magnetic Synchronous Motor) has been increasingly used in many high performance application due to its advantages of high power density, high power factor and efficiency. Firstly, a SVPWM scheme, vector control method and fuzzy controller are derived and applied in the speed control IC of PMSM drive.
