Solar Powered PV Stand-alone Based DC Motor Drive Using Fuzzy Logic Control

Due to rapidly aging electric transmission power and distribution infrastructure, increased demand for energy, awareness of climate change and greenhouse gas pollution, and increased cost of fuel there is a need to produce and deliver energy more efficiently power. This paper attempts to provide a solution to these constraints through advancements in DC power architectures. The simulation study of PI controller for boost converter are presented in a stand alone photovoltaic energy scheme. Moreover the simulation for a DC motor is presented in photovoltaic generator. The complete system consists of an array of solar panels, a boost converter with PI and DC shunt motor with Fuzzy Logic controller (FLC) ? as a voltage regulator. The Fuzzy Logic Controller is designed to deal with the system nonlinearity and its associated uncertainty. DC-DC converters are used to convert the unregulated DC input into a regulated DC output at desired voltage level. The duty cycle (D) of the converter is adjusted to obtain a constant level of voltage or a variable voltage rout in case of voltage regulator or maximum power respectively.
