Abstract
The invention relates to an arrangement and a method for converting an input signal v into an output signal p(r) by using an electro-mechanical transducer and for reducing nonlinear total distortion pin said output signal p(r), whereas the nonlinear total distortion pcontains multi-modal distortion uwhich are generated by nonlinear partial vibration of mechanical transducer components. An identification system generates distributed parameters Pof a nonlinear wave model (N) and lumped parameters Pof a network model (N) based on electrical, mechanical or acoustical state variables of transducer measured by a sensor. The nonlinear wave model distinguishes between activation modes and transfer modes, whereas the activation modes affect the transfer modes, which transfer the input signal u into the output signal p. A control system synthesizes based on the physical modeling and identified parameters Pand Pnonlinear distortion signals vand vwhich are supplied with the input signal v to the transducer and compensate for the distortion signals uand ugenerated by the transducer nonlinearities.
