Today, home appliance applications require more and more features such as motor speed adaptations to multipurpose accessories, user-friendly interfaces, and security features. Such new requirements can be achieved through a low-end microcontroller-based electronic control using the fuzzy logic approach. Now a days, most of fuzzy logic-based controls are only limited to a complicated ranking management of user interfaces, sensors, and actuators, corresponding to slow software speed operation. This paper proposes a totally different use of fuzzy ....etc

INTRODUCTION :-

PLC is a digitally operating electronic apparatus which uses a programmable (through dedicated language such as Relay Ladder Programming) memory for the internal storage of instructions for implementing specific functions such as logic, sequencing, timing, counting and arithmetic to control through digital or analog input output modules, various types of machines and processes.
The programmable controllers (PC) have developed as the heart of the automation of the industries. The PCs offer a number of advantages over th ....etc

In this context, FL (Fuzzy Logic) is a problem-solving control system methodology that lends itself to implementation in systems ranging from simple, small, embedded micro-controllers to large, networked, multi-channel PC or workstation-based data acquisition and control systems. It can be implemented in hardware, software, or a combination of both. FL provides a simple way to arrive at a definite conclusion based upon vague, ambiguous, imprecise, noisy, or missing input information. FL's approach to control problems mimics how a person would m ....etc

Introduction
Fuzzy control is a practical alternative for a variety of challenging control applications since it provides a convenient method for constructing non-linear controllers via the use of heuristic information. Since heuristic information may come from an operator who has acted as a human in the loop controller for a process. In the fuzzy control design methodology, a set of rules on how to control the process is written down and then it is incorporated into a fuzzy controller that emulates the decision making process of the human. ....etc

With the advent of modern computer technology, the field of Artificial Intelligence is showing a definite utility in all spectrum of life. In the field of control, there is always a need for optimality with improved controller performance. In this paper, the feasibility of Fuzzy Logic as an effective control tool for DC motors is dealt with.

This Fuzzy Logic Controller (FLC) is showing a better performance than conventional controllers in the form of increased robustness.

In this paper, the role of Fuzzy Logic as a controller and its imp ....etc

Introduction

In the satellite launch vehicle, the Avionics system is proposed to be based on MIL-STD 1553B BUS. A number of interface modules for application such as sensor data acquisition, vehicle sequencing, control generation, command posting etc. are being designed with this interface. These interface modules are then connected to the onboard computers via the 1553B BUS. These modules have to be tested separately and evaluated and also confirm their compliance with the 1553B BUS standard before being integrated as the Avionics System. T ....etc

COMPLEX PROGRAMMABLE LOGIC DEVICE


As chip densities increased, it was natural for the PLD manufacturers to evolve their products into larger (logically, but not necessarily physically) parts called Complex Programmable Logic Devices (CPLDs). For most practical purposes, CPLDs can be thought of as multiple PLDs (plus some programmable interconnect) in a single chip. The larger size of a CPLD allows we to implement either more logic equations or a more complicated design. In fact, these chips are large enough to replace dozens of the pesky p ....etc
