Adaptive field oriented control of an induction machine using a one-step ahead controller

A new adaptive control algorithm for the field-oriented control of a CSI-fed induction machine is presented in this paper. This includes an adaptive flux model for determining the position and magnitude of the rotor field vector. This online estimation of field vector requires the measurements of stator voltage and rotor speed. The algorithm has been tested by simulating the machine using a digital computer and the results are presented. This scheme is being tested on the machine inverter set up, controlled by a micro computer.
