Design of a DSP-based biaxial solar tracking system

This paper focuses on design a digital signal processor based (DSP-based) biaxial solar tracking system to control the voltage and current to track the maximum power point. The efficiency of the solar tracker is affected by the solar elevation and azimuth angles. Therefore, the principle of passive tracking system is that the rotation angle and tilt angle of the solar tracker is controlled according to the entrained different longitude, latitude, and time. In this paper, the PD-like fuzzy controller is designed to control the motor to complete the maximum poser point tracking (MPPT). Finally, the different methods are implemented to validate the effectiveness of the proposed method PD-like fuzzy controller with the developed solar tracking system.
