The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

So far we have discussed the PI tuning problem in the context of a linear system. This is because under steady-state conditions when the system transients settle out, you will probably be operating in ...

Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...

The course consists of three weeks of materials and is focused on modeling and control of grid-tied power electronics. Upon completion of the course, you will be able to understand, analyze, model, ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...
