Abstract
This paper presents a high speed digital signal processor (DSP) based
system architecture for motor drive control.? The system achieves fast speed
performance by using the 50 MHz TMS320C25 DSP and specialized digital
hardware to perform data acquisition and output control tasks usually
performed in software.? The peripheral hardware has been designed for easy
interface to many types of motor drive systems, to make the system generally
applicable in the motion control field.? The specifications, systematic design,
and realization of this general purpose controller are described.? Software to
support the features of the system is discussed.? Experimental results using
the proposed system to control a switched reluctance motor drive, both in
torque mode and four quadrant speed operation, verify the speed
performance of the DSP based system.
