1.4.1 General objective 
The main objective of this Msc thesis work is study, design, and simulate self-tuning scheme 
fuzzy PID temperature controller of electric furnace which is used for glass tempering process. 
1.4.2 
 
Specific objective
 
The specific objective of this thesis work is: 
 
To study different temperature control mechanisms of glass tempering furnace. 
 
To model electric furnace for temperature control. 
 
To design temperature control system for glass tempering process. 
 
To simulate the temperature control system using MATLAB. 
 
To analyze and compare the performance of fuzzy PID controller with conventional 
PID controller for glass tempering

1.5 Outline of the thesis
This thesis is organized into five chapters. The first chapter presents the overview of 
temperature control mechanisms of glass tempering furnace, statement of the problem, 
relevance and objectives of the study. 
In chapter two, different literatures, related to glass tempering systems and their temperature 
control system, are reviewed. Besides, the basic of fuzzy and PID controllers are also reviewed. 
System modeling, designing and analysis are presented in chapter three. Simulation and 
experimental results are presented and discussed in chapter four. Finally, chapter five presents 
conclusions and recommendations
