System and method for turbomachinery rotor and blade prognostics and diagnostics

摘要

Systems and methods include actuation system of turbomachinery that include an actuator configured to control pitch of vanes of the turbomachinery and a positioner configured to position the actuator to control the pitch. The actuation system also includes a controller system communicably coupled to the positioner. The controller system is configured to drive the positioner based at least in part on a set point of the turbomachinery and obtain data from the positioner indicating an amount of force used for a target pitch. Using the data, the controlling system derives an operating condition for the turbomachinery and controls the turbomachinery based at least in part on the operating condition of the turbomachinery.
