Intelligent Actuation Devices and Distributed Control
by Daniel Halloran, Controls and Electronics Section HeadA significant shift in the fundamental architecture of industrial control systems is slowly taking shape. This shift is from a control architecture focused on PCs and PLCs to one featuring intelligent actuation devices and distributed control. The new paradigm is made possible by high-performance actuation devices that embed integrated closed-loop motion control and a high-speed, digital, network capable, bus interface.
An example of this concept is a hydraulic Injection Molding machine using Moog’s distributed control valves and other network devices. This article fully explains this concept and the evolving technologies that are central to distributed motion control.
