Design of High Precision Tracking System for Light Source Based on TMS320F2812

The traditional SCM control system has the shortcomings such as slow processing speed and tracking accuracy, etc. The paper designs and presents a dual axis light source tracking system. The system uses TMS320F2812 as the controller core to set up a complete system which analyzes and processes the gathered signals, then controls stepper motor to drive the platform, and finally makes system track light source conveniently and accurately. Experimental results show that the system has good effect in tracking speed, precision and disturbance rejection.
