Abstract:
1. A method for controlling a motorized system comprising: measuring an attribute of the motorized system, the attribute comprises at least one of vibration, speed, temperature, pressure, and current in the motorized system; diagnosing a health of the motorized system based on the measured attribute; providing a diagnostics signal based on the diagnosed health; prognosing a state of the motorized system based at least in part on the at least one sensed attribute and/or the diagnosed state; providing a control signal based at least in part on the diagnosed health and the prognosed state; and providing a feedback operation that adjusts the control signal to extend the lifetime of the motorized system to a specific time horizon, the control signal is adjusted based upon at least one of reaching a pre-determined pump cavitation amount or reaching a pre-determined pump blockage amount.
