FLC based photovoltaic battery diesel hybrid system management and control

In this paper, the basic configuration of the fuzzy logic controller (FLC) is introduced and the component functions are illustrated. The proposed block diagram of the PVBD hybrid system control is configured. The system controller manipulated variable as well as the actuators were clearly defined where all the system disturbances are included in the proposed block diagram. The system operation algorithm as well as the FLC algorithm is introduced. The FLC input-variables membership functions as well as the output consequences are illustrated with their universe of discourses. The FLC is tested and simulated by fuzzy logic toolbox under MatLab using first order with delay time process model under variable input signals. The FLC is implemented in the 8051 series microcontroller based on the low level language (assembly) usage. The normalization of the input sensed signals, output commands as well as the signal conditioning circuits are developed and implemented.
