Claim 10:
11. A system for estimating, in-situ and in real-time, actuator parameters for an actuator, the system comprising:
a test signal generator configured to generate a test signal imperceptible to a user of a device comprising the actuator in order to drive the actuator during real-time operation of the device; and
a measurement subsystem configured to:
measure a voltage and a current associated with the actuator and caused by the test signal;
determine one or more parameters of the actuator based on the voltage and the current;
determine an actuator type of the actuator based on the one or more parameters; and
control a playback signal to the actuator based on the actuator type.
