Apr 28, 2006
Appl. No.:
11/413780
Inventors:
Alexei V. Smirnov - Fort Collins CO, US
Assignee:
Advanced Energy Industries, Inc. - Fort Collins CO
International Classification:
G06F 19/00
US Classification:
700 37, 700 28, 700 32, 700 42, 700282, 137 2, 137486, 702100
Abstract:
A system and method for controlling a flow of a fluid using an adaptive closed-loop-control algorithm is described. One embodiment includes a method for receiving a set point indicator and/or a sensor indicator generated by a sensor. A response time of a closed-loop-control algorithm is modified when at least one threshold value is satisfied based on the sensor indicator and/or the set point indicator. The closed-loop-control algorithm, which is implemented by a flow controller, is stabilized in response to the modifying of the response time of the closed-loop-control algorithm by adjusting at least one parameter associated with the closed-loop-control algorithm.

US Patent:
7640078, Dec 29, 2009
Filed:
Jul 5, 2006
Appl. No.:
11/481228
Inventors:
Alexei V. Smirnov - Fort Collins CO, US
Assignee:
Advanced Energy Industries, Inc. - Fort Collins CO
International Classification:
G05D 7/00
G05D 11/00
G05B 13/02
US Classification:
700282, 700 40, 700 75, 137 12
Abstract:
A system and method for controlling a flow of a fluid using a multi-mode control algorithm is described. One embodiment includes a method for changing the multi-mode control algorithm from a closed-loop mode to an open-loop mode. The method includes receiving at least one sensor indicator generated by a sensor. The multi-mode control algorithm is modified from the closed-loop mode to the open-loop mode when, based on the at least one sensor indicator, the threshold condition is satisfied. The multi-mode control algorithm is used by a flow controller to control a flow of a fluid according to a set point.

One thermal sensor is adapted to output a signal which is unaffected by external longitudinal and orthogonal thermal gradients. In one embodiment, the mass flow controller thermal sensor comprises a capillary tube having an upstream tube portion, a tube bend portion, and a downstream tube portion, the downstream portion being substantially parallel to the upstream portion. A distance between the upstream tube portion and the downstream tube portion in one embodiment is no greater than half the upstream portion and downstream portion lengths, a first pair of thermal sensing elements are coupled to the upstream tube portion and a second pair of thermal sensing elements are coupled to the downstream tube portion.

View page
US Patent:
7971604, Jul 5, 2011
Filed:
Apr 20, 2006
Appl. No.:
11/407837
Inventors:
R. Michael McDonald - Fort Collins CO, US
Alexei V. Smirnov - Fort Collins CO, US
Brian Lee - Fort Collins CO, US
Michael John Zolock - Berthoud CO, US
Assignee:
Hitachi Metals, Ltd. - Tokyo
International Classification:
B67D 7/30
US Classification:
1374875, 137486, 222 14
Abstract:
A system and method for delivering a specified-quantity of a fluid using a flow controller based on a fluid delivery profile is described. One embodiment includes a fluid delivery profile that includes a delivery time window with a plurality of set points that each correspond with a specified instant in time within the delivery time window. The method also includes delivering the fluid according to the fluid delivery profile through a variable valve using the flow controller and a feedback signal from a flow sensor.

Adaptive On-Tool Mass Flow Controller Tuning

View page
US Patent:
8131400, Mar 6, 2012
Filed:
Jun 10, 2010
Appl. No.:
12/797753
Inventors:
Alexei V. Smirnov - Fort Collins CO, US
Assignee:
Hitachi Metals, Ltd. - Tokyo
International Classification:
G05D 7/00
G05B 13/02
US Classification:
700282, 700 37, 700 46, 702 50, 702100, 137 2, 137486, 73 116, 73861
Abstract:
One embodiment comprises a method of providing accurate mass flow controller flow rate data for a non-manufacturing-tuning-gas. The mass flow controller may be operated at a setpoint greater than 50%. Data may be recorded to a mass flow controller memory. The setpoint may then be changed to 0%. The recorded data may then be analyzed and one or more non-manufacturing-tuning-gas correction algorithm parameters may be calculated. The one or more non-manufacturing-tuning-gas correction algorithm parameters may be stored in a mass flow controller memory and subsequently used in at least one future mass flow controller operation involving the non-manufacturing-tuning-gas.
