Sinusoidal Control of PMSM Motors with dsPIC30F DSC

From Microchip Technology, Inc.
 

 
This application note describes a method of driving a sensored Permanent Magnet Synchronous Motor (PMSM) with sinusoidal currents controlled by a dsPIC30F Digital Signal Controller (DSC). The motor control firmware uses the dsPIC30F peripherals while the mathematical computations are performed by the DSP engine. The firmware is written in 'C' language, with some subroutines in assembly to take advantage of the special DSP operations of the dsPIC30F. The dsPIC30F Motor Control family is specifically designed to control the most popular types of motors, including AC Induction Motors (ACIM), Brushed DC Motors (BDC), Brushless DC Motors (BLDC) and Permanent Magnet Synchronous Motors (PMSM), to list a few. Several application notes have been published for ACIM operation (AN984, AN908 and GS004) and Brushless DC Motor Control operation (AN901, AN957 and AN992) based on the dsPIC30F motor control family.
