Abstract
Providing wear-related prognostics and diagnostics on a turbine engine includes, while operating a turbine control device, tracking a total device travel distance over time by recurrently: selectively identifying actual device movement based on device position data associated with a displacement sensor monitoring the turbine control device; and accumulating an incremental device travel distance corresponding to the identified actual device movement with the total device travel distance.
Claims26
A driver communicatively coupled to a turbine control device and a turbine engine control unit (ECU), the driver comprising a memory, a processor, and instructions stored in the memory and operable when executed by the processor to cause the driver to perform operations comprising:
- operating the turbine control device by recurrently:
- receiving a demand signal from the turbine ECU;
- and
- determining and transmitting a desired position to the turbine control device based on the demand signal;
- and
- during the operating of the turbine control device, tracking a total device travel distance over time by recurrently:
- selectively identifying actual device movement based on device position data associated with a displacement sensor monitoring the turbine control device;
- and
- accumulating an incremental device travel distance corresponding to the identified actual device movement with the total device travel distance.
A computer-implemented method for providing wear-related prognostics and diagnostics on a turbine engine, the method being executed using one or more processors and comprising:
- operating a turbine control device by recurrently:
- receiving a demand signal from a turbine engine control unit (ECU);
- and
- determining and transmitting a desired position to the turbine control device based on the demand signal;
- and
- during the operating of the turbine control device, tracking a total device travel distance over time by recurrently:
- selectively identifying actual device movement based on device position data associated with a displacement sensor monitoring the turbine control device;
- and
- accumulating an incremental device travel distance corresponding to the identified actual device movement with the total device travel distance.
A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for providing wear-related prognostics and diagnostics on a turbine engine, the operations comprising:
- operating a turbine control device by recurrently:
- receiving a demand signal from a turbine engine control unit (ECU);
- and
- determining and transmitting a desired position to the turbine control device based on the demand signal;
- and
- during the operating of the turbine control device, tracking a total device travel distance over time by recurrently:
- selectively identifying actual device movement based on device position data associated with a displacement sensor monitoring the turbine control device;
- and
- accumulating an incremental device travel distance corresponding to the identified actual device movement with the total device travel distance.
