Abstract
This paper presents a deadbeat flux controller for vector control induction motor drives. Efficiency of an induction motor is improved when the magnitude of the rotor flux is changed according to a load. In order to obtain high efficiency drives of an induction motor spoiling the speed response, a method to control the rotor flux with the deadbeat response is proposed. The theoretical analysis, design and computer simulations of the proposed drive are presented. The simulation results show excellent performance of the proposed system. To verify the proposed deadbeat torque control concept, a laboratory setup with a four-pole 1.5 hp induction motor drive with dSPACE DS1102 laboratory control board is constructed. The experimental results confirm the validity of the proposed control scheme. Copyright (c) 2012 Praise Worthy Prize S.r.l. - All rights reserved.
