Abstract :
Waveform optimization attempts to solve a constrained optimization problem for current waveforms that produce no torque ripple with minimum copper losses. In doing so, it must also solve the high velocity problem at limited voltage. This paper computes the maximum torque-speed profile achievable under such constraints, and it also demonstrates a fast numerical technique for solving waveforms that are smooth and roughly optimal
