Special Projects on Control
Topic : MATLAB Simulink
What is Simulink ?
• Simulink is a software package that enables you to model, simulate and analyze systems whose outputs change over time
• Simulating a dynamic system is a two-step processes with Simulink : – create a graphical model using the Simulink model editor.
– use Simulink to simulate the behavior of the system over a specified time span.
Starting Simulink
1. Starting MATLAB1. Click the Simulink icon
2. Enter the simulink command
Creating a model
1. An easy example• Using signal generator and scope to measure a
sine wave signal
2. An example of the first order system
