A Simplified SVM-DTC Algorithm Based on Integral Derivative Sliding Mode Control for Electrical Machines

Abstract

This paper presents a novel approach for achieving high-speed processing of Integral Derivative Sliding Mode Speed Controller (IDSMSC) based Space Vector Modulation Direct Torque Control (SVM-DTC) algorithm using a Field-Programmable Gate Arrays (FPGA) for controlling an Induction Motor (IM). As a first contribution in this work, the proposed IDSMSC aims to enhance the dynamic response and robustness of IM drive through the utilization of IDSMSC technique, known for its superior performance in tracking reference signals and rejecting disturbances. The second contribution consists in implementing the proposed SVM-DTC-IDSMSC algorithm on an FPGA platform. Indeed, significant improvements in processing speed and real-time responsiveness will be attained, enabling efficient execution of complex control strategies. In fact, the integration of FPGA technology ensures precise timing synchronization and parallel processing capabilities, facilitating rapid computation of control actions with minimal latency, which consequently reduce the ripples in the torque and the harmonics in the current. Through simulation studies using Xilinx System Generator toolbox under Matlab environment and performance analysis, the effectiveness and feasibility of the proposed approach are demonstrated, highlighting its potential for high-performance control applications in industrial settings.
