Control of machinery with calibrated performance model

A system for controlling a machine, the system comprising:

• a system controller in communication with a monitoring system of the machine, the system controller being operable to:
• calculate, using a performance model of the machine, a set of inter-stage conditions of the machine corresponding to a set of input conditions and a set of output conditions during an operation of the machine, wherein the machine includes a turbine component having a fluid path therein traversing a plurality of turbine stages and a plurality of inter-stage positions, wherein each of the set of input conditions, the set of output conditions, and the set of inter-stage conditions includes one of a temperature, a pressure, and a flow rate, and
• calibrate the performance model of the machine based on a difference between a predicted value in the performance model of the machine and one of the set of input conditions and the set of output conditions;
• and
• a control valve operably coupled to the system controller and an inlet of the turbine component, the control valve being operable to adjust an operating parameter of the machine based on the calibrated performance model and the calculated set of inter-stage conditions of the machine.

A program product stored on a non-transitory computer readable storage medium for controlling a machine, the non-transitory computer readable storage medium comprising program code for causing a computer system to:

• calculate, using a performance model of the machine, a set of inter-stage conditions of the machine corresponding to a set of input conditions and a set of output conditions during an operation of the machine, wherein the machine includes a turbine component having a fluid path therein traversing a plurality of turbine stages and a plurality of inter-stage positions, wherein each of the set of input conditions, the set of output conditions, and the set of inter-stage conditions includes one of a temperature, a pressure, and a flow rate;
• calibrate the performance model of the machine based on a difference between a predicted value in the performance model of the machine and one of the set of input conditions and the set of output conditions;
• and
• adjust an operating parameter of the machine based on the calibrated performance model and the calculated set of inter-stage conditions of the machine.
