Motorized system integrated control and diagnostics using vibration, pressure, temperature, speed, and/or current analysis
First Claim
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.

Abstract
Systems and methods are disclosed for controlling, diagnosing and prognosing the health of a motorized system. The systems may comprise a diagnostics system, a prognostic system and a controller, wherein the diagnostics system and/or prognostic system employs a neural network, an expert system, and/or a data fusion component in order to assess and/or prognose the health of the motorized system according to one or more attributes associated therewith. The controller may operate the motorized system in accordance with a setpoint and/or a diagnostics signal from the diagnostics system and/or prognostic information. Also disclosed are methodologies for controlling, diagnosing and prognosing the health of a motorized system, comprising operating a motor in the motorized system in a controlled fashion, diagnosing and/or prognosing the health of the motorized system according to a measured attribute associated with the motorized system, wherein the motor may be operated according to a setpoint and/or the diagnostics signal and/or prognosis.
