A NEW SLIP GAIN ADAPTATION ALGORITHM FOR INDIRECT FIELD-ORIENTED DRIVE SYSTEMS

Abstract

A new adaptation algorithm of the slip gain in the indirect field-oriented controller for the induction machine using the current-regulated PWM inverter is presented. This algorithm is based on the direct decomposition into d(c) and q(c) components for the synchronously rotating compensated reference frame where the d(c) axis is aligned with the axis of actual rotor flux. The proposed algorithm is verified through digital simulation.
