Abstract: A non-transitory computer readable medium may have stored thereon data encoding a waveform signal for playback, wherein the waveform signal is generated by implementing a discrete time model of a physical electromagnetic load that emulates a virtual electromagnetic load and modifying a raw waveform signal to generate a waveform signal for driving the physical electromagnetic load by modifying the virtual electromagnetic load to have a desired characteristic and applying the discrete time model to the raw waveform signal to generate the waveform signal for driving the physical electromagnetic load.

Abstract: A method for identifying a mechanical impedance of an electromagnetic load may include generating a waveform signal for driving an electromagnetic load and, during driving of the electromagnetic load by the waveform signal or a signal derived therefrom, receiving a current signal representative of a current associated with the electromagnetic load and a back electromotive force signal representative of a back electromotive force associated with the electromagnetic load. The method may also include implementing an adaptive filter to identify parameters of the mechanical impedance of the electromagnetic load, wherein an input of a coefficient control for adapting coefficients of the adaptive filter is a first signal derived from the back electromotive force signal and a target of the coefficient control for adapting coefficients of the adaptive filter is a second signal derived from the current signal.
