Modelling and control of Boeing 777-300 ER<br />

Introduction<br />

This dissertation gives an overall simple idea on modelling and control of an aircraft, the respective advantages and<br />

disadvantages used for the Matlab/Simulink on analyzing aircraft system. This paper presents the tests using the data of<br />

Fixed wing aircraft Boeing 777-300ER as it is one of the biggest commercial aircraft in the world which is matching the goal<br />

of the project, to give a safety traveling experience for human. The main aim of the project is to produce a generic procedure to<br />

identify a dynamic model from flight simulator and demonstrated with Matlab/Simulink software and to provide a demo procedure<br />

and manual for potential users. The Aircraft<br />

Base on the information from Boeing (<strong>2015</strong>) [1], Boeing 777 is the largest twin engines fixed wing<br />

aircraft in the world and has a seating capacity for 301 to 386 passengers. The 777 family consists of<br />

six different models, with the ability to fly point-to-point non-stop to bypass crowded and busy hub<br />

airports. It has a range capability of 9,700 km to 17,395 km.<br />

The Boeing-300ER is one of the models in 777’s family with the largest range while ER is the name<br />

stands for extended range. It features raked and extended wingtips with a wing aspect ratio of 9.0.<br />

The Boeing 777-300ER is powered with an increased fuel capacity and a maximum thrust of 115,300<br />

lbf (513 kN) and the maximum range is 14,492 km. The Boeing 777-300ER can fly approximately 34<br />

percent farther than the Boeing 777-300 with a full load of passengers and cargo. The first -300ER<br />

was delivered to Air France on April 29, 2004 and it is the best-selling 777 variant, having surpassed<br />

the Boeing 777-200ER. Based on the report of world airliner census (2014) [3], there are 493<br />

Project summary<br />

The process of modelling and control of<br />

system for the aircraft is often done by<br />

using a computer, using the data of<br />

aircraft performance. Where the process<br />

is normally of continuous time nature and<br />

the dynamical system is mostly describes<br />

in terms of the differential equations. This<br />

dissertation presents recent<br />

developments in the modelling and<br />

control using flight simulator to collect the<br />

data and Matlab/Simulink software to<br />

analysis<br />

Project Objectives<br />

• Review up-to-date art of Merlin flight<br />

simulator and Boeing 777-300ER.<br />

• Learning to operate the<br />

Malab/Simulink to prepare step by step<br />

manual.<br />

• Present basic flight dynamic and<br />

modelling techniques.<br />

• Collect relevant data from<br />

Matlab/Simulink.<br />

• Develop Matlab programs to fit the<br />

proposed dynamic models with the<br />

measured data.<br />

• Prepare a user-friendly demo/program<br />

manual.<br />

Project Conclusion<br />

Based on the demands of modern human<br />

society, aircrafts have become more and<br />

more complicated. By getting aircraft data<br />

from the internet or Java-foil, aircraft<br />

performance can be simulated with the<br />

use of excel or Matlab/simulink. This<br />

paper has written to give a belief idea on<br />

how modelling and control of an aircraft is<br />

and to provide a user-friendly demo for<br />

public user.
