Maximum Power Point Tracking (MPPT) helps to reduce the oscillation around maximum power point
(MPP) and enhances the efficiency of the Photovoltaic (PV) system. Two Degree of Freedom PID (2-DOFPID)
based MPPT controller is implemented to generate adequate gate pulse for DC-DC converter. Sine
Cosine Algorithm (SCA) is a new optimization technique, which is adopted to elect the relevant best values
of the gain parameters of both 2-DOF-PID and PID controllers for better the performance. The performance
of proposed controller is validated with the Fuzzy logic controller (FLC), Proportional Integral Derivative
controller (PID) and Perturb & Observation (P& O).
