Abstract

The paper presents a digital simulation and validation study of an error driven tri-loop Fuzzy Logic Controller FLC with motor load current limiting loop for a hybrid photovoltaic PV farm utilization with an alternative power source for DC type loads. A three loop dynamic error driven fuzzy logic controller is designed and validated for the control of the required power transfer to the composite DC-load under normal as well as abnormal disturbance based excursions and changes. The basic characteristic of the FLC controller is the catering to any nonlinear Load Inertia and Damping J, B as well as sudden load torque excursions and surges. The proposed control function is digitally simulated using the MATLAB/Simulink/SimPower System software environment. The dynamic performance of the unified green energy PV-DC utilization system is fully examined for the control system validation under normal and abnormal operating conditions.
