Abstract
Official abstract text for this publication.
Methods are provided for ensuring non-excessive variation of a gradient of an applied split bias versus firing temperature of a gas turbine engine. It is determined that an incremental split bias step is to be taken, and a current firing temperature of the gas turbine engine is identified on a graph. A first difference between a split schedule and an applied schedule gradient is calculated using lower firing temperatures than the current firing temperature, and a second difference is calculated using higher firing temperatures. If the first difference exceeds a predetermined limit, the incremental split bias step is not allowed at a lower firing temperature, and similarly, if the second difference exceeds a predetermined limit, the incremental split bias step is not allowed at a higher firing temperature.
First claim
Opening claim text (preview).
What is claimed is: 1. One or more non-transitory computer-readable media that, when invoked by computer-executable instructions, perform a method for ensuring non-excessive variation of a gradient of an applied split bias versus firing temperature of a gas turbine engine, the method comprising: determining that an incremental split bias step is to be taken during automatic tuning of the gas turbine engine; identifying a current firing temperature of the gas turbine engine on a…
