Patent ID: 8332071

Claim:
A method for calibrating an actuator comprising an energy converter and a transducer, the energy converter being characterized by a first and a second interrelated parameters and the transducer being characterized by a transducing ratio, the method comprising: coupling a first sensor to the output of the energy converter to measure values of the first and second interrelated parameters; operating the energy converter by providing a plurality of activation signals of different values; constructing at least one interrelated parameters curve using outputs provided by the first sensor; coupling the transducer to the energy converter to thereby form the actuator; coupling a second sensor to the output of the transducer; operating the actuator by providing a plurality of activation signals of different values; constructing an internal losses model of the actuator using outputs provided by the second sensor; coupling a static load to output of the transducer; operating the actuator by providing a plurality of activation signals of different values; and, obtaining static load calibration to obtain external loses model of the actuator.
