Comparison of Stabilization Methods for V/f controlled Induction Motor Drive System

摘要

This paper investigates a study of different stabilization methods for open-loop controlled induction machines. Many approaches of stabilization were proposed, which were almost exclusively based on the same principle: the stator current derivative feedbacks to the stator voltage. In this paper, the feasible types of feedback are discussed and the optimal solution can be found by utilizing a new analytical procedure. A comparison is given with roots loci study. The result of the analysis is proved with experiment.
