PI Observer for Sensorless Field Oriented Control of Permanent Magnet Synchronous Motor

The angular velocity and rotor position of the motor are computed by PI observer. Clark and Park transformations is utilized to establish a dynamics model of the motor. Space vector pulse width modulation algorithm is used for voltage modulation. The main control chip of the hardware board selects TI's TMS320F28035, and the power device selects Mitsubishi's IPM(PS22A79). The hardware board is designed to test and verify the PI observer. The test results are analyzed and indicated that the PI observer is a good candidate for sensorless field oriented control of permanent magnet synchronous motor.
