Experimental Implementation of Direct Torque Control of Induction Machine on FPGA

摘要

In this paper, we present a design method of Direct Torque Control based on hardware description language and FPGA implementation. The DTC, which is used to control induction machines, is designed through the description of Concordia transformation, torque and stator flux estimator, torque and stator flux comparator, stator flux position detector, switching table and Finite State Machine (FSM). The same algorithm is designed and simulated using MATLAB software tool to make a comparison with the proposed design on FPGA. Experimental test results of this drive control structure realized in FPGA are demonstrated.
