ChallengeSimplify the operation of forage harvesters by automating the process of

filling trailers with corn, grass, and other crops

SolutionUse Model-Based Design to develop, test, and implement an automated

control system that uses 3D camera data to position the filler spout

Results Development times halved

Generated code immediately operational

Industry innovation award won

IntelliFill™ system from CNH’s

FR90000 series

“With Model-Based Design we spent most of

our time developing and optimizing the system.

Almost no time was spent implementing it in C

or debugging code. There’s no difference in

performance between the Simulink model

running on a laptop and production code.”

Why use Model-Based Design?For you as an Engineer

“Model-Based Design enables the simulation of complex

mechatronic systems and controllers, code generation for

real-time HIL testing, signal and image processing, and

data analysis and visualization.”

Example: Engineering Problem to Solve

Control the actuation of

part of a robotic system

Electric motor with

velocity control

8

What Kind of Insights Do We Want to Get?

How do I size the motors?

Does my system still work if component values change?

Can I get desired performance?

What if…?
