In order to improve the efficiency of solar panels, this paper designs a DSP-based two-degree of freedom point light source fuzzy tracking system,which is based on the fuzzy reasoning technology and digital signal processor technology. It designs a photodiode based light source detection unit,and uses a two-degree of freedom steering gear PTZ as the execution unit. By analysis characteristics of the system and summing up the experience,it gave a set of fuzzy control rules,and determined some important control parameters. Considering the real-time control,and system stability,it uses the DSP as the core of the system control unit. Simulation and experiments results show the good performance of the system.
