AB  - Feed forward nonlinear error correction of loudspeakers can improve sound quality. For creating a realistic feed forward strategy identification of the loudspeaker parameters is needed. The strategy of the compensator is that the nonlinear behaviour of the loudspeakers has relatively small drift and only the linear loudspeaker parameters must be identified. This can in music systems be done with online transducer-less system identification using the voice coil current as feedback from the loudspeaker (plant). This is investigated in a simulation study for finding useful system identification algorithms. Two different identification techniques (ARMA and FIR) are compared. The stability of the nonlinearities and linear loudspeaker parameters are tested in a measurement series.
