AB  - Feed forward methods for compensation of nonlinearities in loudspeakers are studied and tested in simulation cases. An adaptive feed forward controller is investigated to handle the drift caused by temperature, ageing and production spread. For estimating the needed parameter accuracy (match between controller and plant parameters) we have tested a simple feed forward controller with different degree off parameter mistuning between plant (loudspeaker) and controller. The required system identification (tracking of the changes in linear loudspeaker parameters) is investigated using and simple 2nd order IIR model for the linear loudspeaker. Different techniques to handle the stability problem for adaptive IIR filters are investigated.
