ABSTRACT
The purpose of this paper is to present the
design of DSP-based vector and current controllers
for a PMSM drive. Several different implementations
of the vector controller are evaluated and the
consequent effect on the maximum motor speed
examined. A careful choice of the cosine look-up
table which is used in the vector controller is
presented. The possibility of implementing a
hysteresis current controller algorithm using the
DSP is also evaluated. The layout of a PC board
including the DSP chip, latches and PAL chips to
decode the 1/0 ports is included as well.
Experimental results are provided.
