A method of high efficient control for induction motor

Abstract

This paper proposes the controlling method for induction motor operating at high efficiency in transient state. We propose a method of current control to minimize stator current in case of giving torque we want. First of all, we understood problems of vector controlled for induction motor and suggest methods to solve these problems. In the simulation, the efficiency in the transient state is evaluated by comparing the copper loss between two methods. © 2009 SICE.
