Pack more performance and power into every closed-loop system

In applications where fractions of a second can make or break system stability, we enable the sensing, processing, control and communication necessary to implement and optimize real-time control. Through decades of expertise and leading-edge technology, we empower designers to reduce the size, complexity and cost of their systems by helping them achieve the highest reliability, efficiency and performance possible.

What is real-time control and why do you need it?

Every day, people interact with systems that assess their surroundings and act accordingly; where those systems are implementing what’s known as “real-time control.”  In this article, we explain the functional blocks of a real-time control system and provide an example of a robotics application.
