Abstract

In order to get good dynamic performance, induction motor adopts constant rated flux for vector control in servo system. However the motor has lower efficiency especially at light load. If the motor controlled with adjustable flux for maximum efficiency, its dynamic performance can not meet the demand of the system. The research is to solve the mutual conditionality of dynamic rapidity and high efficiency. A flux regulator has been added in vector control. It is controlled by speed and requiring torque, and timely adjusts flux to keep good dynamic performance and high efficiency. The simulation results of a case verify the validity and feasibility of the proposed approach.
