Design and Co-Simulation Of A Quadcopter Stabilisation System
Introduction:
This project will investigate Quadcopter dynamics and flight characteristics and a suitable
simulation of a stabilisation system will be produced. The main idea is to use two different
software packages (Scade Suite and Matlab/Simulink) and getting them to communicate in
real-time to produce the simulation as opposed to using just one program. Aspects
addressed will include the production of the stablisation system, understanding and building
certain models using both software packages and finally building a connection or bridging
both programs to get them to communicate and produce the simulation in real-time. Analysis
of the system as a whole and the results obtained is also addressed in this report.
Over the years small Unmanned Aerial Vehicles or better referred to as simply UAVs have
become more and more popular. The size of these vehicles as well as the nature in which
they operate makes them perfect for carrying out a variety of tasks ranging from dangerous
military bombing runs or surveillance missions to simple academia related experiments for
research.
Outline:
Aspects from both models are shown in the figures including the Plant model, one of the PID
controllers, an animation GUI used and the communication protocol considered
Project summary
The aim of the project was to create a control system
for a quadcopter UAV, using two different types of
software; Simulink and Scade Suite.
Project Objectives
There were two main goals;
1. Create a quadcopter model in two halves within
Scade Suite and Simulink, the model will use PID
control and State Space representation to model
the Quadcopter.
2. Create a network connection between the two
tools to allow communication between both.
Project Conclusion
The First objective was achieved and a suitable
prototype of the Plant and Control models were
constructed.
The second part was unsuccessful as real-time
communication between both tools is almost
unachievable. There are alternatives however as
Scade can generate suitable code for integration in
Simulink using S-Functions.
