MIT Students Use LabVIEW and CompactRIO to Design and
Implement a Dynamic Output Feedback Controller
• Challenge: Giving students the tools to implement control designs on real-
world hardware, including a simulation environment for prototyping and
validating their controllers to help overcome the challenges of moving from
theory to practice.

• Solution: Using NI LabVIEW software and CompactRIO hardware as a control
platform to design and prototype controllers in simulation and implement them
in real-world systems using a unified software architecture that easily takes

students from the simulation environment and with a toggle switch on the
LabVIEW front panel to deploy their controller to the physical hardware.

• Products: CompactRIO, LabVIEW Real-Time Module, FPGA Module,
MathScript RT Module, Control Design and Simulation Module, LabVIEW
“Overall, the LabVIEW framework gave students the freedom to take greater control of the hardware
controller design process.” - Professor Jonathan How - Massachusetts Institute of Technology

Building a Semiautonomous Vehicle Driven by the
Visually Impaired with LabVIEW and CompactRIO

Application: A system to build and program the world's first
functional prototype of a blind driver vehicle.

Challenge: Developing a semiautonomous vehicle that allows
a blind driver to successfully navigate, control speed, and
avoid collision through a secure driving course.

Products: cRIO-9072, NI 9485, NI 9263, LabVIEW, Real-Time
Module, NI 9221, FPGA Module, CompactRIO

Key Benefit: The intuitive graphical programming interface of
LabVIEW made it easy for a team of undergraduate
mechanical engineering students to quickly and efficiently
create custom embedded software without the need for
expertise in any specific text-based programming
language.

"With limited funding and development time, NI products played a vital role in the project success by
providing an easy-to-use and cost-effective prototyping platform.“ - Greg Jannaman - Virginia Polytechnic
Institute and State University

Developing a Telemetry System for a Solar Car
• Challenge: Developing a low-power, real-time monitoring
system for a solar car traveling 3,000 km in the World Solar
Challenge to monitor the health of the vehicle and help
optimize our race strategy.

• Solution: Using an NI CompactRIO controller and an 8-slot
chassis to monitor the voltage, current, temperature, and
speed of the vehicle and transmitting this information
wirelessly using a 2.4 GHz modem to a chase vehicle
following the solar car.

• Products: NI 9401, LabVIEW, FPGA Module, NI 9870, NI
9219, cRIO-9014, NI 9211, cRIO-9104, NI-VISA, NI-Serial
"We chose CompactRIO because it combines real-time data acquisition on customizable input channels
and can record and transmit data.“ - Neo Wei Ren - School of Mechanical Engineering, Nanyang
Technological University

Developing a Low-Cost Computer Numerical Controller Using
NI Motion Controllers and NI LabWindows™/CVI Software

• Challenge: Creating a low-cost computer numerical
controller (CNC) system with extremely high speed
and accuracy for use in industrial shipyards around the
world.

• Solution: Using NI motion controllers and NI software
to build a flexible, low-cost system to meet a variety of
customer specifications.
"By using an NI motion controller and taking advantage of extensive NI customer support, we
created software which makes the CNC less expensive, easy to install, and widely applicable in our
industry."
– Khanh Phan Van, Institute of Applied Mechanics and Informatics

TriQuint Semiconductor Uses NI PXI and LabVIEW to Reduce
RF Power Amplifier Characterization Time

• Challenge: Reducing the characterization time of increasingly complex
cellular power amplifiers (PAs) without sacrificing measurement accuracy
or incurring higher capital equipment costs.

• Solution: Using NI LabVIEW software with NI PXI modular
instrumentation to develop a PA characterization system that helped us
improve test throughput by 10 times while still reducing capital equipment
cost, power consumption, and physical space.

• Products: NI TestStand, LabVIEW, PXI-4071, NI PXIe-5442, PXI-5690,
NI PXIe-5673, NI PXIe-5122, PXI-2596, NI PXIe-5663, PXI-4110

“With NI PXI, we were able to reduce the characterization time of new parts from
two weeks to about a day.” —Gary Shipley—TriQuint Semiconductor
