Iron losses predominate in automotive traction applications at partial load and thus significantly in driving cycles. In this work, iron losses and overall drive losses of saturated salient pole synchronous machines are minimized by optimal control of flux linkage, in magnitude and waveform. Loss minimizing flux magnitude is calculated in real-time including copper-, inverter- and iron losses. By...
DB-DTFC is a flux-observer-based high bandwidth digital, closed-loop torque control law that achieves the commanded torque at the end of each switching period. When flux estimation is accurate, instantaneous torque is fed back and unwanted pulsating torque is inherently minimized. This research presents real time flux-observer-based torque ripple estimation of a highly nonlinear synchronous reluctance...
The elastic modulus of a deposit (Ed) can be obtained by monitoring the temperature (ΔT) and curvature (Δk) of a one-side coated long plate, namely, a onedimensional (1D) deformation model. The aim of this research is to design an experimental setup that proves whether a 1D deformation model can be scaled for complex geometries. The setup includes a laser displacement sensor mounted on a robotic...
