Traditionally, closed-loop servo motor control is handled by J6-bit, high-end microcontrollers and external logic. In an attempt to increase performance many applications are upgrading to DSPs. However, the recent introduction of very high performance 8-bit micro controllers with high through-put features makes it possible to implement these servo control applications at a significant reduction in cost. This paper describes the design issues and trade-offs involved in using these processors to control a DC brush motor using a PID algorithm. The low cost of the overall system allows it to compete favorably with stepper motor systems.
