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, ...
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.
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 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 ...
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 ...
Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current ...
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 ...
