Abstract

The design of DSP-based vector and current controllers for a permanent magnet synchronous motor (PMSM) drive is presented. Several different implementations of the vector controller are evaluated, and the consequent effect on the maximum motor speed is 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 the DSP chip, latches, and PAL chips to decode the I/O ports is included as well. Experimental results are provided.<>
