1.3 Objective
The main objective of this project is to control and model multiple tank fluid level control system using Fuzzy Controller. In order to achieve the main objective,
following are some additional objectives to be completed: a
To evaluate the current fluid level control. b
To design and propose an automatic fluid level control system that can replace the current mechanical system.
c To control and simulate the designed Lamella Filtration tank fluid control
system.
1.4 Scopes
The scopes of this project are: a
Data Collection A case study will be conducted to collect data about the current Lamella
Filtration system at Bukit Sebukor Water Treatment Plant Malacca. In this case study, a few visits will be pay to the Bukit Sebukor Water
Treatment Plant, and the technician on duty will be interview for the data collection purpose. After that limitation of the current system will be
identify and carefully taken into consideration for the further improvement. Besides that, data for literature review will be collect from
internet, books, and previous student’s research.
4 b
Design and Simulation New automation control system will be designed to improve the current
system. The new control system will be design by using Fuzzy Logic Toolbox in Matlab. The designed system will then be simulated.

CHAPTER 2
LITERATURE REVIEW
2.1 Introduction
The literature review that have been done to gain more information on the project that been carried out is describes in this chapter. Firstly, the basic explanation on the
control system is discussed. After that, it is followed by the discussion of the lamella filtration tank fluid level control and the devices that needed in controlling this
system. Finally is the control application using the Fuzzy Logic Toolbox with the aid of Matlab is discussed.
Mechanical controls are used to control the simple level and flow system, for the examples: limit switches, mechanical valve, and electro-pneumatic valve. However,
mechanical system could not give an accurate and precise output in controlling. Further more, the mechanical control performance are affected by the tear and wear
process. Automation control by the application of control system can be used to achieve a better performance.
