Performance Analysis of Field-Oriented Control and Direct Torque Control for Sensorless Induction Motor Drives

Authors : Sellami Said , Belkacem Sebti and Naceri Farid

Abstract: This study presents a contribution for detailed comparison between two sensorless control techniques for high performance induction motor drives: Field-Oriented Control (FOC) and Direct Torque Control (DTC). The main characteristics of field-oriented control and direct torque control schemes are studied by simulation emphasizing their advantages and disadvantages. The performances of the two control schemes are evaluated in terms of torque and current ripples and transient responses to load toque variation. We can nevertheless say that the two control schemes provide in their basic configuration, comparable performances regarding the torque control and parameter sensitivity. We can note a slight advance of DTC scheme compared to FOC scheme regarding the dynamic flux control performance and the implementation complexity. The choice of one or the other scheme will depend mainly on specific requirements of the application.
