A computer-implemented method for determining the health of an actuator has been filed as a patent, with the primary objective of assessing the actuator's condition based on various signals captured during operation. The method involves applying power to the actuator, capturing signals related to movement and force, determining inertial and load force values, and ultimately deriving a health value for the actuator. This health value serves as an indicator of the actuator's overall condition, providing valuable insights into its performance and potential issues.

Furthermore, the patent includes additional claims related to determining low acceleration, calculating load force values based on captured signals, and utilizing predetermined values for mass and acceleration in the calculations. The method also involves providing indicators to users based on the health value, allowing for real-time monitoring and assessment of the actuator's health. Additionally, the patent extends to systems and turbine control systems that implement these methods, showcasing a comprehensive approach to evaluating and maintaining the health of actuators in various applications. Overall, the patent presents a detailed and systematic method for assessing actuator health, with potential implications for improving operational efficiency and maintenance practices in a wide range of industries.
