Abstract
A method for determining a direct current impedance of a transducer may include receiving an input signal indicative of an electrical power consumed by the transducer and calculating, by a thermal model of the transducer, the direct current impedance based on the electrical power.
Claims28
A method for determining a direct current impedance of a transducer, comprising:
- receiving an input signal indicative of an electrical power consumed by the transducer;
- and
- calculating, by a thermal model of the transducer, the direct current impedance based on the electrical power.
A system comprising:
- a transducer;
- and
- a control system for monitoring operation of the transducer and configured to determine a direct current impedance of a transducer by:
- receiving an input signal indicative of an electrical power consumed by the transducer;
- and
- calculating, by a thermal model of the transducer implemented by the control system, the direct current impedance based on the electrical power.
