Processor in the Loop Comparative Study of Indirect Rotor Field Oriented Control, Direct Self Control, Direct Torque Control and Space Vector Modulation Based Direct Torque Control for Induction Motor Drives

Abstract

This work proposes a design and implementation, using Processor In the Loop technique, of several control strategies of the induction motor. Therefore, this paper offers a validation, by experimentation, of Direct Self Control, Direct Torque Control and its variants, Space Vector Modulation based Direct Torque Control and Indirect Rotor Field Oriented Control. These control strategies are also compared by waveforms quality, switching frequency and complexity of the algorithms running in an actual Digital Signal Processor. For code generation and algorithm validation, MATLAB/Simulink R2017b and Code Composer Studio are used. For implementation, LAUNCHXL-F28069M development board, based on TMS320F28069 from Texas instruments, is chosen. Results of this comparative study, using Processor In the Loop technique, show that Space Vector Modulation based Direct Torque Control strategy offers the best performances compared to the other Direct Torque Control strategies; and it is, in addition, less complex than the Indirect Rotor Field Oriented Control strategy.
