Abstract:
Commercial made solar trackers are a nice addition to any solar panel array. They help increase the time that panels directly face the sun and allow them to produce their maximum power. Unfortunately they can be expensive to buy. We decided to make our own solar tracker to see if we could reduce the cost. We did not want to re-invent the wheel but wanted to make it more affordable. We started out small and came up with the idea of solar tracking using time instead of using a device that would sense where the sun is and move th ....etc

A new control scheme for a single ? phase diode clamped rectifier is proposed to achieve a unity power factor, balanced neutral point voltage and constant DC-bus voltage. Four power switches are used in the rectifier to generate a three-level PWM wave form on the rectifier terminal voltage.

The line current command is derived from a DC-link voltage regulator and an output power estimator. The hysteresis current Controller is used to track the line current command. To balance the neutral-point voltage, a capacitor voltage compensator is emplo ....etc

Abstract

“Solar Panel Maximum Power Point Tracker”. As the name implied, it is a photovoltaic system that uses the photovoltaic array as a source of electrical power supply and since every photovoltaic (PV) array has an optimum operating point, called the maximum power point, which varies depending on cell temperature, the insolation level and array voltage. A maximum power point tracker (MPPT) is needed to operate the PV array at its maximum power poi ....etc

i have attached a solar tracking report i read on the internet. wanting to implement this project as my final year project, i want some help in the fuzzy logic design. i some how didnot understand how it is used and how it can be implemented.

pooja

P.S: i need help ASAP ....etc

Abstract
The following document details the research and development of an Automatic Solar radiation tracker. Fossil fuels are a relatively short-term energy source; consequently, the uses of alternative sources such as solar energy are becoming more wide spread. To make solar energy more viable, the efficiency of solar array systems must be maximized. A feasible approach to maximizing the efficiency of solar array systems is ....etc

Fuzzy Logic and Fuzzy Sets 


History


Lotfi Zadeh, at the University of California at Berkeley, first presented fuzzy logic in the mid-1960's.

Zadeh developed fuzzy logic as a way of processing data. Instead of requiring a data element to be either a member or non-member of a set, he introduced the idea of partial set membership.

In 1974 Mamdani and Assilian used fuzzy logic to regulate a steam engine.

In 1985 researchers at Bell laboratories ....etc
