Digital Regulation of Accelerator Power Supplies Design How-To 9/23/2002 Post a comment Particle accelerators require magnet power supplies with very high performance. Digital technology advances have made it possible to implement very complicated regulation schemes using DSPs or PLDs. Hooman Hassanzadegan presents a new digital-regulation scheme based on state estimation that may replace traditional analog PID regulators. The article presents a state-space model of the proposed system, including power supply, regulator, and estimator, along with Matlab and Simulink simulations.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
