getting to smart

Experimentation system that is: – easy to use

– transparent in operation

– and flexible

Finite-state machine execution with interfaces

to C++, ROS, and MATLAB

MATLAB: – quadrotor modeling, control design, trajectory planning, simulation

– interface for experiment definition and execution

Continual development of increasingly complex behaviors

Design Reuse

“We‟re using the same models to control different systems.

It benefits us to use these [models], single sources that

people can understand; it allows us to go faster.”

organization

smart│ decisions

HKM optimize a steel production process

smart│ organization

Constraints – complex process

– equipment capability

– raw material availability

– environmental regulations

– demands of multiple customers

Previously: – dispatcher scheduled entire plant manually

– required extensive process knowledge - only a few qualified

– significant business risk If dispatcher is absent

Manually reviewed plant schedule

Plant schedule automatically optimized with MATLAB

HKM algorithms at work


Develop algorithm – Algorithm development accelerated by a factor of 10

– Optimization time cut from 1 hour to 5 minutes

Deploy algorithm – integrate into HKM‟s existing scheduling application.

getting to smart

Scale to fit: from prototyping ideas to

24/7 number-crunching

“In some cases the automated system

has produced a solution that our

dispatchers did not consider.”

Deploy knowledge to others in the

organization


Parallel Computing Toolbox and MATLAB

Distributed Computing Server – Multiple cores to computing clusters

– The number of GPU-enabled MATLAB

functions continues to grow in

– GPU-enabled functions can be

deployed using MATLAB Compiler

MATLAB Mobile – iPhone and iPad

– Access „in the field‟

Do you….

… have a strong foundation of algorithms and components

to build “smart” systems?

… use models to share ideas and verify implementations?

… organize to develop product lines with re-used components?

… coordinate your research and product development teams?

… put algorithms and decision-making tools

in the hands of all the right people?

… educate students with theory, modeling, hands-on practice,

and a systems perspective?

… hire for those skills and build them in your teams?

Enjoy the conference!
