MODEL BASED DESIGN

WHAT IS MODEL BASED DESIGN Methodology to design complex systems

Using models and simulation Using tools for automation




14

Introduction to SimulinkThe leading environment for modeling, simulating, and implementing dynamic and embedded systems

Block-diagram environment

Model, simulate and analyze systems with many components

Accurately design, implement, and test:– Control systems– Signal

processing systems

– Communications systems

– And other dynamic systems

PHYSICAL MODELLING TOOLS

Simscape

Model and simulate multidomain physical systems.

Simscape™ enables you to rapidly create models of physical systems within the Simulink® environment.

With Simscape you build physical component models based on physical connections that directly integrate with block diagrams and other modeling paradigms.




Why model a physical system?

Example: humanoid robot arm

–

What are the actuation requirements?

Space and weight constraints Torque/force, speed & power Compliance Precision Dynamic tracking bandwidth Failure behaviour

Which actuation technology?

––

What is the impact on the rest of the system

Power supply requirements Heat Electromagnetic interference

3

System model with selectable detailed & behavioural sub-models

Behavioural model of actuation system

System-level model of complete system

Indian Institute of Technology Delhi Integrates MATLAB Throughout Master’s Level Mechanical Engineering Curriculum •Screenshot from an animation created by the MATLAB based software ReDySim (Recursive Dynamics Simulator).•“We wanted software our students could use for numerical computation, mathematical modeling, and data visualization. •The software had to be easy to learn, interactive,• applicable to many disciplines, and useful for years to come.• MATLAB fulfilled all those objectives and more.”

Dr. Subir Kumar Saha, Indian Institute of Technology Delhi

Tata Motors Develops Engine Management System for Tata Nano, the World’s Least Expensive Car

• The Tata Nano.•“Prototyping with Model-Based Design proved essential. •With an integrated platform for modeling, simulation, and testing, we could rapidly make changes and predict how the whole system would react before it was built. •This early insight shaped the design of the controller, engine, and Nano itself.”S Govindarajan, Tata Motors
