Research on the tracker controller methodologies in utilization of solar energy

This paper sorts tracker controller methodologies in utilization of solar energy into close loop, open loop, and hybrid. Solving and substituting into the equation, the tracking angle of several single\|axis tracking modes can be gained. By relations between hour angle and the tracking angle of several single\|axis tracking modes, selecting for controller methodologies of several single\|axis tracking modes are acquired. By using MATLAB to deal with data, the figures of relations between hour angel and the tracking angle of horizontal N/S tracking can be worked out, and at this time feasibility and applicability of hybrid tracking control system are analyzed. Merits and demerit of several tracker controller methodologies are studied and summarized, and characteristic and applicability of them are researched.
