US Patent:

7966080, Jun 21, 2011

Filed:

Jun 8, 2010

Appl. No.:

12/795758

Inventors:

Jianhu Jia - Cedar Park TX, US
Stephen Piche - Austin TX, US
W. Hardey Beaver - Austin TX, US

Assignee:

Pegasus Technologies, Inc. - Mentor OH

International Classification:

G05B 13/02

US Classification:

700 29, 700 36, 700 44, 700274

Abstract:

A method and apparatus for controlling a parameter associated with operation of a fossil fuel fired power generating unit. An optimizer determines optimal setpoint values for manipulated variables used to operate the power generating unit by accessing a model that predicts a parameter sensed by a plurality of sensors. The optimizer uses the model to minimize a cost valve of a cost function while observing at least one constraint associated with operation of the power generating unit.
