Teaching DSP servo-motor control with extended SHARC evaluation boards; the Pilot-Fish project

In this paper, the authors discuss a locally-generated daughter-board extension to the popular SHARC DSP evaluation module (EVM). The board improves the performance of this inexpensive hardware in many applications that involve feedback control. They discuss the use of this hardware in a simple servomotor control experiment that demonstrates many of the fundamentals of digital signal processor control of physical plants.
