Implementing a PID Controller Using a PIC18 MCU


INTRODUCTION
Continuous processes have been controlled by
feedback loops since the late 1700’s. In 1788, James
Watt used a flyball governor on his steam engine to
regulate its speed. The Taylor Instrument Company
implemented the first fully functional Proportional,
Integral and Derivative (PID) controller in 1940.
Although feedback control has come a long way since
James Watt, the basic approach and system elements
have ..............etc

ABSTRACT
Through our project we are showing the control of constant temperature according to the desired value (set point) in a closed loop using PID controller system. For this, we are using a microcontroller, a temperature sensor for sensing the temperature of the closed loops. By using the microcontroller we compare the desired value with current value and it is displayed in the LCD. Also to provide the constant temperature, Fan or Heater is turned On or Off according with the variations of current temperature ..............etc

Abstract
The paper describes the Fuzzy–PID cascade controller to control the level of horizontal tank that has diameter 300 mm and 480 mm long. Interface card module PCI-6024E in computer and Lab View software program is used for built the cascade controller. Structure of its where the inner loop is a PID controller for regulating flow rate of system and outer loop is a Fuzzy logic controller for control the level. The response time, steady state error, load disturbance, and control valve action of cascade are tested and compared wit..............etc

INTRODUCTION
In spite of developed modern control techniques like fuzzy logic controllers or neural networks controllers, PID controllers constitute an important part at industrial control systems so any improvement in PID design and implementation methodology has a serious potential to be used at industrial engineering applications. At industrial applications the PID controllers are preferred widespread due to its robust characteristics against changes at the system model. From the other side at industry the exact plant m..............etc

ABSTRACT
In this study, a design methodology is introduced that
blends the classical PID and the fuzzy controllers in an
intelligent way and thus a new intelligent hybrid
controller has been achieved. Basically, in this design
methodology, the classical PID and fuzzy controller
have been combined by a blending mechanism that
depends on a certain function of actuating error.
Moreover, an intelligent switching scheme is induced

INTRODUCTION TO PLC
1. Programmable Logic Controller
A Programmable Logic Controller, or PLC for short, is simply a special computer device used for industrial control systems. They are used in many industries such as oil refineries, manufacturing lines, conveyor systems and so on. Where ever there is a need to control devices the PLC provides a flexible way to software the components together.
The basic units have a CPU (a computer processor) that is dedicated to run one program that monitors a series of differen..............etc
