Abstract:

Direct Torque Control (DTC) is a state of the art control methodology for induction motor drives which features very favorable control performance and implementation properties. However, one of its main deficiencies is the lack of a systematic design procedure for the inverter switching table which is the core of the control system. This issue is addressed in this paper, where we propose a novel modelling and control approach for the DTC problem based on a systematic design procedure. The DTC drive, comprising a two- or three-level dc-link inverter driving a three-phase induction motor, is modelled in the hybrid Mixed Logical Dynamical (MLD) framework, and a constrained finite-time optimal control problem is set up and solved over a receding horizon using Model Predictive Control (MPC). Simulation results are provided and compared to the current industrial state of the art demonstrating the potential for notable performance improvements.
