A new direct torque control for reduced energy consumption in induction motors Article uri icon

abstract

  • This document proposes an energetic output improvement of electric drives for induction motors. This modification pointing toward a better energetic output (improving the efficiency) according to the application, and can be made in the most common control algorithms as the FOC (Flux Oriented Control) and the DTC (Direct Torque Control). The simulation results show that the proposed controller ensures both, a good speed control and smooth torque response with current shapes with low THD, when these are compared with the conventional DTC scheme. Experimental results for a 1.1 kW induction motor are presented and analyzed using a dSpace system with DS1103 controller board based on digital processor Texas Instruments TMS320F240. Obtained results demonstrated that the proposed control scheme is able to obtain a high performance. The increase in drive%27s efficiency supposes on the one hand, a considerable economic saving and, on the other hand, a reduction in the environment pollution. © 2010 Praise Worthy Prize S.r.l. - All rights reserved.
