MFA Control Toolset for NI LabVIEW™

What's New
What's the Big Deal
What's the Benefit
Embedded Model-Free Adaptive (MFA) controllers inside LabVIEW environment. An integrated control solution that leverages your investment in NI's products and software platforms. Offers NI users an enhanced control capability delivered as part of the LabVIEW solution.


Left: When MFA (top) and PID (bottom) start from the same oscillating control condition, PID will continue to oscillate while MFA will quickly adapt to an excellent control condition. Both MFA and PID are running in a FieldPoint device. Right: MFA controllers inside NI's PXI system.

NI - MFA Product Options
Embedded MFA Inside LabVIEW
MFA controls the processes that are too difficult for PID controllers to handle. MFA is the only "No Model" advanced controller on the market that can control complex systems without the use of first-principle mathematical models or dynamic modeling based models. Once installed, no controller parameter tuning is required.

Better control means improved process stability, higher production efficiency and yield, consistent product quality, and reduced material and energy waste.
