A SYSTEM AND A MEHTOD FOR INVERTER POWER SWITCHING CONTROL FOR REDUCTION IN ELECTROMAGNETIC TORQUE RIPPLE IN A THREE PHASE INDUCTION MOTOR DRIVE

摘要

A system and a method for inverter power switching control for reduction in electromagnetic torque ripple in a three phase induction motor drive comprising the steps of driving a three phase induction motor ,estimating the rotor speed and stator flux ,comparing the reference rotor speed and stator flux with the estimated rotor speed and stator flux and processing the errors with corresponding Proportional and Proportional-Integrating controller and controlling the device switching pattern in the inverter by thus processed error.
