An Enhanced Electric Vehicle with modified Predictive Direct Torque Control of Open Winding Permanent Magnet Synchronous Motor Drive

Abstract

Direct Torque Control (DTC) is a popular method for controlling the Permanent Magnet Synchronous Motor (PMSM) Drive. However, high torque and flux ripples are a disadvantage of DTC. It is observable that PMSM drive with Predictive Direct Torque Control (PDTC) function produces smaller torque and flux ripples, attaining better responsiveness under various steady-state and dynamic circumstances. This work proposes a low complexity PDTC-based technique for direct regulation of flux and torque of an Open Winding (OW) PMSM drive. Two unique cost-functions for regulating flux and torque are employed in this suggested PDTC without involving a weighting component. For the OW-PMSM Drive, this simplified technique offers an enhanced steady state response. To verify this, simulation model is created in the MATLAB-2020a Simulink platform. Comparative simulations of the suggested control with DTC are performed in terms of steady state and dynamic properties.
