CONSTRAINED NONLINEAR PARAMETER ESTIMATION FOR ROBUST NONLINEAR LOUDSPEAKER MODELING FOR THE PURPOSE OF SMART LIMITING

CONSTRAINED NONLINEAR PARAMETER ESTIMATION FOR ROBUST NONLINEAR LOUDSPEAKER MODELING FOR THE PURPOSE OF SMART LIMITING

A non-linear excursion estimations system for estimating non-linear excursion of a loudspeaker may include a loudspeaker having a force transducer, and a controller programmed to limit excursion of the loudspeaker by modeling at least one constrained nonlinearity curve based on an asymptote outside...

Zusammenfassung:A non-linear excursion estimations system for estimating non-linear excursion of a loudspeaker may include a loudspeaker having a force transducer, and a controller programmed to limit excursion of the loudspeaker by modeling at least one constrained nonlinearity curve based on an asymptote outside of a safe operating area (SOA) nonlinearly curve of the loudspeaker.
