Abstract
The invention relates to an arrangement and method for estimating the linear and nonlinear parameters of a modeldescribing a transducerwhich converts input signals x(t) into output signals y(t) (e.g., electrical, mechanical or acoustical signals). Transducers of this kind are primarily actuators (loudspeakers) and sensors (microphones), but also electrical systems for storing, transmitting and converting signals. The model describes the internal states of the transducer and the transfer behavior between input and output both in the small-and large-signal domain. This information is the basis for measurement applications, quality assessment, failure diagnostics and for controlling the transducer actively. The identification of linear and nonlinear parameters Pand Pof the model without systematic error (bias) is the objective of the current invention. This is achieved by using a transformation systemto estimate the linear parameters Pand the nonlinear parameters Pwith separate cost functions.
