Simulink and MATLAB

1
Simulink and MATLAB

• TELFOR 2003

2
Modeling, Simulating, Analyzing

• The most widely used software package in academia
  and industry
• Modeling and simulating dynamic systems
• Build MIMO models from scratch
• Simulations are interactive (change parameters
  on the fly)
• Instant access to all the tools in MATLAB

3
MIMO systems

• multiple-inputs multiple-outputs

4
Hierarchical Systems

• View the system at a high level
• Double-click block - go down through the levels
• Insight into how a model is organized, how its
  parts interact

5
Starting Simulink

• Start MATLAB
• Click the Simulink icon on MATLAB toolbarEnter
  the simulink command at the MATLAB prompt
• Starting Simulink displays the Simulink Library
  Browser

6
Simulink Library Browser

• Displays a tree-structured view of the Simulink
  block libraries

7
Signal Generator

• Generate various waveforms
• Parameters and Dialog Box

8
Simulation Parameters

• Set the simulation parameters by choosing
  Simulation Parameters from the Simulation menu

9
Starting the Simulation
CtrlT

• Pull down the Simulation menu and choose the
  Start command (or CtrlT)

10
Blocksets

• Blocksets are specialized collections of Simulink
  blocks built for solving particular classes of
  problems

11
DSP Blockset

• DSP Blockset design and simulate DSP systems
• The DSP Blockset provides the algorithmic
  foundation for many applications in the areas of
  speech and audio processing, telephony,
  wireless, digital communications and control,
  radar/sonar, and medical electronics

12
Benefits

• Provides graphical user interface for building
  models as block diagrams, using click-and-drag
  mouse operations
• Supports linear and nonlinear systems
• Modeling in continuous time, sampled time
• Subsystems can be multirate and MIMO
• Short software development cycle
