Deadbeat Predictive Direct Torque and Active Flux Control with Disturbance Observer

This paper proposes a new framework for the deadbeat predictive direct torque control for interior permanent magnet synchronous machine (IPMSM) utilizing active flux. Unlike the existing deadbeat predictive direct torque and stator flux control, it is relatively simple and does not require to neglect any physical quantities such as stator resistance votlage drop and cross-coupling. In addition, a sliding-mode-disturbance-observer (SMDO) is combined to track the system disturbances caused by parameter mismatch in real time. The effectiveness of the proposed composite control is verified by simulation and experiment results.
