Fuzzy based controller for solar photovoltaic powered butter extraction system

Majority of people in India live in villages and main source of income comes from agriculture. Many houses in the villages possess cattle of different varieties and milk products such as curd, butter yield additional income. Traditionally butter is extracted by manually churning curd. This paper proposes an autonomous system based on fuzzy logic principles to extract maximum butter minimum time. The apparatus for butter extraction consists of a PV panel, DC-DC converter and a d.c. motor. The butter extraction is conceived as a non-linear process and relevant inputs and outputs are mapped into fuzzy sets. The rule base is then designed. The proposed scheme is validated through simulation results.
