Abstract

A model reference speed adaptive controller for a current-fed induction motor drive is proposed. It uses a proportional-plus-integral (PI) adaptation to satisfy the hyperstability condition for taking care of the load and machine parameter changes of the drive. The available information on the states and output of the reference model as well as the plant output are all that are required for the control; no explicit parameter identification is needed. The controller can be designed by using a reduced reference model to simplify the design without much degradation of the performance, so that it is relatively easy to implement practically
