Patent number: 11199824Abstract: A control technique controls a process in a manner that reduces the number of controller changes provided to a controlled device, and so reduces the power consumption of the controlled device along with the loading of a process control communications network disposed between the controller and the controlled device. This technique is very useful in a control system having wirelessly connected field devices, such as sensors and valves which, in many cases, operate off of battery power. Moreover, the control technique is useful in implementing a control system in which control signals are subject to intermittent, non-synchronized or significantly delayed communications and/or in a control system that receives intermittent, non-synchronized or significantly delayed process variable measurements to be used as feedback signals in the performance of closed-loop control.Type: GrantFiled: March 19, 2015Date of Patent: December 14, 2021Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Terrence L. Blevins, Mark J. Nixon, Kurtis K. Jensen, Mitchell S. Panther, Deji Chen, Eric D. Rotvold

Publication number: 20210341327Abstract: Methods and apparatus for quantifying pneumatic volume usage via valve controllers are disclosed. An example apparatus includes a valve controller operatively couplable to a pneumatic actuator, the pneumatic actuator being operatively coupled to a control valve. In response to an input signal indicating that a flow control member of the control valve is to be moved in a specified direction, the valve controller commands a current-to-pressure (I/P) converter of the valve controller to pulse a relay valve of the valve controller between a closed position and an open position. The pulsing of the relay valve causes the pneumatic actuator to move the flow control member in the specified direction. The valve controller calculates a pneumatic volume usage associated with the moving of the flow control member in the specified direction. The pneumatic volume usage is based on the pulsing of the relay valve.Type: ApplicationFiled: April 30, 2020Publication date: November 4, 2021Inventors: Kurtis K. Jensen, Michael R. Fontaine
