Loss Minimizing Strategy of Permanent Magnet Synchronous Machines using Improved Direct Torque and Flux Control

Beschreibung

This thesis presents the loss minimization strategies utilizing improved torque and flux control for interior permanent magnet synchronous machines (IPMSMs). As a loss minimization method of the system based on the control strategy, the widely accepted direct torque control (DTC), field oriented control (FOC) and finite control set model predictive torque control (FCS-MPTC) are investigated and analyzed. Meanwhile, a nonlinear loss model control (LMC) is developed and integrated into the control strategies. Furthermore, a novel discrete-time machine model which is based on improved Euler method and an alternative deadbeat (DB)-MPTC with FCS are developed.
