Normally, lookup-table-based methods are being utilized for loss-minimizing control of permanent magnet synchronous motors (PMSMs). But numerous repetitive experiments are required to make a lookup table, and the program size becomes bulky. In this paper, analytic methods for finding the loss-minimizing solution are studied. Since the solution lies either in the interior or on the voltage limit boundary,...
Normally, look-up table based methods are being utilized for loss minimizing control of permanent magnet synchronous motors (PMSMs). But, numerous repetitive experiments are required to make a look-up table, and the program size becomes bulky. In this work, analytic methods of finding the loss minimizing solution are studied.

A loss minimizing control law is developed for a fuel cell electric vehicle (FCEV) permanent magnet synchronous motor (PMSM) which reflects the effects of field saturation and cross coupling. Inductances are modelled as functions of q-axis current based on the flux data obtained experimentally. For a given torque and a given speed, the loss minimizing current sets are searched from the experimental...
