- 2. 2 What will you learn in this presentation? For those who are not familiar with Simulink and for those who are about to start using Simulink, you might have been wondering: In this presentation you will be able to find out the answers to these questions. • What is Simulink? • Why Simulink? • Where and how can Simulink be used?
- 3. 3 What is Simulink? An Environment for Modelling and Simulation.
- 4. 4 What is the purpose of modelling and simulation in the first place? To run tests that are impossible or hard to reproduce with the actual object in the real world. – Dangerous – High Cost – Physically Impossible / Difficult To investigate the functionality and performance of the phenomenon in interest. – Insights of Physics Based Phenomenon – Parameter Study – Visualization of Phenomenon that are not Visible to Eyes.
- 5. 5 Why Simulink? User friendly block diagram environment – Clear data and processing flow. – Easy to realize and to share ideas. Flexible environment that covers a wide range of different application areas – Dynamic System, Event-Driven System. – Physical Modelling, Control System, Signal Processing. Complete integration with MATLAB environment. – Batch simulation by scripts. – Access to various design, analysis and technical computing libraries.
