Why do Model-Based Design (MBD)

Real-Time Simulation & Testing?

It enables you to:

Test, verify, validate, and prove your algorithmic andsystem designs earlier

Evaluate new ideas using a flexible, scalable,production independent development platform

Minimize risk, reduce costs, shorten time-to-market

Achieve determinism through system modeling,automatic code generation and real-timesoftware/hardware execution

ChallengeDesign and develop an unmanned aerial camera

motion system for close-range aerial filming

SolutionUse Model-Based Design with MATLAB and Simulink

to accelerate the design, debugging, and

implementation of the vehicle’s fly-by-wire and flight

management system software

Results Time-to-market shortened by up to an order of

magnitude

Test flight anomalies quickly resolved

Debugging time reduced from weeks to hours

Airnamics Develops Unmanned Aerial

System for Close-Range Filming with

Model-Based Design

Airnamics co-founders Marko Thaler and

Zoran Bjelić with the R5 MSN1 prototype

after its first flight.

Link to user story

“With Model-Based Design our three-

engineer team found more than 95%

of control software bugs before the

first flight. We used the test flights to

increase our Simulink models’

fidelity and isolate remaining bugs

with high precision. The result is a

safer, more reliable, and higher-

quality product.”

Sonova Shortens Product Development

Time for Hearing Aids and Implants with

Model-Based Design

ChallengeShorten development time for new hearing

instruments and implants

SolutionUse Model-Based Design with MATLAB and Simulink to

develop a reusable library of digital signal processing

components, and use Simulink Real-Time for rapid real-

time prototyping and testing of design ideas

Results Real-time prototypes updated in minutes, not days

80% of software libraries reused in platform

Software quality improved

“Across Sonova, engineers from

a variety of backgrounds use

MATLAB and Simulink as a

shared language for designing

innovative signal processing

systems. Model-Based Design

and rapid real-time prototyping

enable us to maintain the

product development pace that

our business demands.”

Cochlear Ltd. Streamlines Development

of Cochlear Implant Sound Processing

Algorithms

ChallengeEvaluate innovative noise-reduction algorithms for

cochlear implants

SolutionUse Simulink to model and simulate candidate

algorithms, and use Simulink Coder with xPC Target to

conduct real-time tests of the most promising candidates

Results Algorithm development overhead reduced by 60%

Six times as many new algorithms tested

Platform integration problems eliminated

“MATLAB, Simulink, and Simulink

Real-Time provide a robust, flexible,

and efficient means of integrating the

many different technologies that

cochlear implants require. We identify

the best ideas faster, and our

recipients experience the

improvements in real-time tests, which

are essential to our research.”

OHB Develops Satellite Guidance,

Navigation, and Control Software for

Autonomous Formation Flying

ChallengeDevelop low-cost satellite GNC systems to enable

autonomous formation flying, rendezvous, and close-

proximity operations with a small team

SolutionUse MathWorks tools for Model-Based Design to model

GNC algorithms, perform real-time simulations, and

generate production flight code

Results Development time cut by 50%

Early verification and test reuse enabled

Interagency collaboration simplified

“Traditionally, control engineers

specify requirements using text and

diagrams and someone else codes

the software. With Model-Based

Design, we have eliminated that step.

We work with models from concept

to implementation, and we have the

automatically generated code flying

in space."
