Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

TOKYO--(BUSINESS WIRE)--Azbil Corporation (TOKYO:6845) has started sales of the model C1A single loop controller, which features high accuracy and fast response and reduces the burden on personnel, ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

In this article, as in industry, advanced process control (APC) refers primarily to multi-variable control. Multivariable control means adjusting multiple single-loop controllers in unison, to meet ...

The release of the NI LabVIEW 8.5 control design and simulation module adds features that help to analyze open-loop model behavior, design closed-loop controllers, simulate systems, and create ...

When model-based multivariable control made its debut in the 1980s, it was expected that process models, once acquired through a plant step test, would be durable and long lived. However, this ...

In some LED lighting applications, precise light intensity control is a must. For instance in shops where multiple LED lighted panels are installed one next to the other, the light intensity and light ...

Controlling hydraulic motion with precision involves understanding the fundamental difference between servo motors and hydraulic actuators. Electric motors generally respond linearly to control inputs ...

With four control modes, including a PID autotune function, along with four output options and 17 alarm types, AutomationDirect’s Solo process/temperature controllers can be used in a variety of ...
